my fx6 stopped working after I done a routine maintenance Ie change sponges etc. After I cleaned the impeller like in this video it now working Thanks for the tip Fluval.
once again fluval Rocks,, I replaced both intake and out takes on my fx6 and the microw bubbles are goneeeeeee, and stopped leaking , also I replaced all orings and greased them, thank you fluval for all your staff help and great customer service as always.
Hi Lisa. I am also having trouble with micro bubbles. I have inspected, cleaned and lubricated all the o rings. I have cut the hoses shorter for fresh ends into the in/out. Checked the impeller.. Still micro bubbles. Did you replace the in/out hoses or the valves on the top of the pump?
I’ll probably have to do this for my fx4. I noticed maybe a month or two ago the water wasn’t running anymore. I haven’t cleaned the filter in a while so I did that but I had no idea about motor maintenance. This helped a lot and I’ll have to buy a spare impeller.
I have the Fx5. It was used when i purchased it, never maintananced until today which is little over a year because it started making noise. I unscrewed the motor, rinsed everything out with the waterhose, no brush needed. Put it back together, noise gone🤷♂️ No rebuild kit needed if nothing is damaged
I have 2 or and a gold fish in the 125 gallon tank , all black filters and foam pads have been changed also, even have added new fluval media ,the propeller has also been checked and cleaned, I order a connect values, one for the intake and out tank, from fluval they will be here on the 14th,
Fluval Aquatics I noticed that it really started dripping when I shut off the outake valve.. Anyway I replaced the O-ring on the same day as my original comment and no problems since. Hopefully future models will have a much bigger and better seal system that can hold up and handle a lot more pressure.
I had the fx6 for a year now , i didnt know that we have to do the impeller. In my next cleaning , is it time to clean my impeller ? Or how soon to have it clean ? Thanks
Hi there! We recommend cleaning the impeller every 3 months, so we'd say you're due to clean it! You'll likely notice an improvement in filter performance once the impeller's been cleaned. 👍
As the only moving part in the filter, it's important to clean and replace the impeller regularly to keep the system running as expected! We recommend cleaning the impeller assembly every 3 months and replacing it on a yearly basis.
So I have a question? Me and my gf have a 125 gallon and a fx6 filter on it. She's had the filter now for a little over 4 years, well a few days ago, it started to make weird noises and then just today my gf messaged me and said that it stopped running completely. We drained it, I took out the motor and cleaned it, put the motor back properly, refilled the filter, and now it won't start. We are thinking of replacing the motor entirely, but I'd like input from the professionals before we make that decision.
Hi Leo, thank you for reaching out! We are sorry to hear that you are having some trouble with your FX filter. Please contact our customer service team regarding this, our team of specialists will be glad to offer you some assistance. 😊 fluvalaquatics.com/us/contact-us/
My FX6 is leaking where the motor is on the left side. I purchased a maintenance kit and changed the o-ring with lubricant and the impeller but it is still leaking. How do I fix this?
My fluval fx4 not working ,not running, impeller not even running either. I have installed a brand new impeller replace the rings as well. I know this Canister reset on its on after plug in, but its been 3 days. Still nothing! What should I do? Please help!
Nice video as always. I have never done this. Is this a routine thing that needs to be done every year or so, or only if it stops working or is makes noise? I am very nervous about this as I can see 15 different things that can go wrong when I do this lol!
Don't be nervous, it's very straightforward! We recommend checking and cleaning the impeller assembly every 3 months - as the only moving piece in the filter, keeping it clean will guarantee the best filtration efficiency! Yearly replacement of the impeller assembly is recommended since the impeller spins 24/7 and does wear over time.
@@fluval Mine ran strong for 3 years, with only some difficulty getting it to prime lately. Totally missed this part of the maintenance and never cleaned it once. Will be replacing all the seals and impeller tomorrow!
Noisy Impeller, suspect the top Bushing is worn out as I can wiggle the bottom plate on the impeller. Am I right to pressume that this indicates that the top bushing is worn out?
Hi Chester, thank you for your comment. A noisy impeller can be due to the impeller itself or the impeller shaft and busing. Please contact our customer service team for further assistance with this. 😊 fluvalaquatics.com/us/contact-us/
It's normal for FX motors to become warm to the touch! This is actually a design choice - as a result of the pump being outside the canister, the heat it generates is not transferred to the aquarium water, helping to keep your fish safe and healthy. 👌 If the motor feels unusually hot, try giving the impeller, impeller shaft and impeller well a thorough cleaning.
hi John, The FX4 is a new release so a slight delay is to be expected. Please visit www.fluvalaquatics.com and enter your country, select the contact page and reach out to us directly, we will help you locate a dealer with stock or will get back to you if the product has not yet arrived in your market.
Hi there! The impeller can't "die", as there are no electrical components to it. Since the impeller is the only moving part in the filter, it does wear over time and therefore requires periodic (yearly) replacement!
I always have a problem with the clips on the fx5 and fx6. When I loosen all the clips and hang them down ,one clip always comes out. It is a pita to put it back onto the canister.
Hi Craig, this may be a faulty fastener, the rubber base may be damaged. A replacement will be needed: FX5 Fastener, item # A20214, FX6 Fastener item # A20215.
Oops I meant to oranda goldfish they are both about 6 inches booth fx6s on the 125 get cleaned on a regular basis all pads have been changed and I'm waiting for my intake and outtake new valves to come in the ones that clip into the filter cuz the outtake Vale is dripping but when I turn the flow down on it it stops also I noticed that the microbubbles stopped when I turn the Val down on the out take tube where it was leaking so maybe it's that. I'm hoping it's that the other fx6s running fine and I got them at the same time I had an Oscar in that tank at one time that's why there's two fx6s on there as I rehomed the Oscar I ended up putting my goldfish in there just too I will be adding two more but they are in a hospital tank right now for a few weeks before I add them
My fx6 impeller is not running smooth. It spins in jerky motion, and does not generate suction. I have cleaned as shown here, as well as verifying multiple times that my inlet and outlet to the pump are clear. There are no blockages. Is there anything else I can do or is this a motor failure that requires replacement
Hi Mike, we're sorry to hear about this. The impeller may indeed be in need of replacement: as the only moving part in the filter, it's recommend to replace it on a yearly basis. We encourage you to contact our customer support team for more assistance: fluvalaquatics.com/us/contact-us
@@fluval I've ordered a fluval impeller kit already. I'm going to try that first, and if it's the motor itself that's failing and the impeller doesn't fix the issue I also ordered an aftermarket motor that fits as a replacement. I'm hoping it's just the impeller and I can return the motor, but this filter has had disappointing flow since day 1 so I wouldn't be surprised if the motor failed. Even when clean and brand new I was only getting about 450gph, with no additional media and only 2ft head height. The impeller didn't appear to have any damage or bending, but I will try a new one with a new bushing to see how that does. Thanks for the feedback.
@@fluval it was the motor itself. The impeller rotates flawlessly in my Chinese knockoff motor that just showed up. Not sure what is failing in my OEM FX6 motor, but it doesn't spin the impeller anymore. For as much as these cost, they oughta last more than 2 years. This one has been disappointing since it came out of the box. I guess a bad motor would explain why.
Hi Ethan! It's normal for the motor to turn itself off once every 12 hours. If you're noticing more frequent interruptions, please contact our customer support team for assistance: fluvalaquatics.com/us/contact-us/
Hi Bobby, Fluval carries a silicone lubricant. You should be able to pick it up at your nearest PetSmart. bit.ly/2b7vzah The FX maintenance schedule in the instruction manual provides some insight as to when you should check and replace. bit.ly/2apYXVr
Sorry to bother you again, just wanting to double check the flow direction in the FX5 please. Should I place mechanical media in the bottom tray, then my bio media in the above 2 trays please? Or bio media in the bottom 2 trays and mechanical media in the top tray please? Sorry, I haven’t had any luck with finding out solid info. Also wondering if there’s an online user manual available please? Thank you once again for any feedback you can provide 😊
The flow through FX filters is as follows: the water first moves to the bottom of the canister, and then rises to the top through the foam pads. It then passes back to the bottom of the canister through the media trays in the middle, before finally being returned to the aquarium. So, you'll want your mechanical filter media on the top tray, and your biological filter media on the bottom 2 trays. You can find the user manual and answers to questions like this here (link is for FX6, but functionally it's the same as the FX5): fluvalaquatics.com/us/product/fx6-high-performance-canister-filter/
@@fluval Thanks for the quick reply. Cheers. The motor block on the this particular motor is the same as my other pumps which are marketed under different brands... I have 4 different pumps and looking at them on my desk and all the same (can interchange impeller, volute, mounting points etc between all of them and they provide different specs according to the parts and application used): The four pumps on my desk are a Red Dragon 1000, Red Dragon 600, Askoll 1500 and a Laguna 1350 which I purchased through Hagen and all are using the same motor block made by Askoll and each pump is modified as per each vendors specifications such as mounting, bearings, volute etc.. so my question again, who makes the Motor block for this particular pump? is it Askoll based on the Askoll 1500 motor block? Fluval Aquatics does not make this motor block unless the patent was purchased from Askoll. Please advise.
@@V1ZFN in italy they seem to sell Fluval products as: Fluval by Askoll so id figure they are a fluval partner? or they own hagen or so. oh hagen owns Fluval, google Fluval aquaclear and Hagen Aquaclear.
It looks like I accidentally broke my FX4 case. Now it leaks out the bottom. The plastic case is cracked. Where can I buy a new case? I have looked on your website, you sell everything except the case. Do I have to buy a whole new filter?
I have a 12 plus year old FX5 that I just replaced the impeller and seals because it would stop working periodically. I cleaned the intake and output hoses as well- nothing was real dirty. The output flow still doesn't feel like the day I got it. Does that mean I need to replace the motor unit now? I have not seen any information about "if" and "when" that would be necessary.
Hi Chris, the motor head doesn't need to be replaced. Try cleaning out the other parts of the filter - it's possible the ribbed hosing needs cleaning, for example!
I have to replace the axel, twice. I fallow the instructions, and happened again !!! The kits are so expensive, and broken so often, for real, the aquarium dirt is the only way to know the filter stop. It’s no fun
My FX4 came with a red rubber cap inside the motor housing . Ive tried to research a ton but dont see anyone with the same red cap as mine does. My fx4 had issues priming everytime i clean it and service the impellar. Any way you could reach and help? Ive only had it 20 months. Thanks

Hi there, we are sorry to hear that you are having some trouble with your filter. Our first suggestion would be to refer to page 7 of the products user manual to ensure that the filter is within the constraints provided in our diagram. The distance from the top of your filter to the waterline in the aquarium should be within 20cm to 150cm and the distance from the water line to the peak of the tubing (top of the aquarium rim) should be no more than 20cm. If your filter is placed within these constraints and is still giving you some trouble, please reach out to our customer service team so that we can investigate this further with you! Below is a link to our customer service team as well as a link to the FX6 product manual, we hope this helps! 😊
I have 2 fx6s on my 125 gallon tank , I've had them both for 2 years now and replaced top cover cick fit o-ring cover ring gasket all suction cups tubing in tank and outtake adapters connects and the motor seal, cause I was getting the mico bubbles and after I did all of that it still does it , if I turn the flow down just a little on the outtake it seems to stop, also the outtake val, is dripping but it also drops once I turn the flow down, I also order 2 new ones , one for intake and out take, if this down work I am ripping the the thing off the tank,
Hi Lisa. This all depends on how often the filter is cleaned, what species of fish you keep (some are obviously dirtier than others), the quantity of fish you keep, and the size of your tank. It's also possible the foam blocks have aged and are perhaps collapsing, especially if a regimented maintenance schedule hasn't been maintained. A Severely clogged filter can be the reason too, in which case you would want to look at replacing the intake and output valves.
I'd actually recommend he buy another brand that has the game GPH, higher bio capacity, withstand user negligence and through all of this runs completely silent. German made - starts with an E.
Hi fluval. I have a fx6. It has don't great from a year and it has been running crappy. I tried cleaning it all out. I bought a new impeller and seals. To try that. I have set it all back up and now it's not doing anything. Any ideas of what could be going on?

Hi Joseph! Both the FX4 and the FX6 would be suitable for that tank size, so it ultimately depends on the tank stocking and your maintenance routine! Remember that you can never over-filter a tank, so we'd recommend the FX6. 👍
I have 2 brand new FX6 for my 140gl just put together yesterday but the water flow is very low and it do noise like I can hear the water noise. Can you help me please. Thank you.
This is likely due to air in the system and not filling the canisters sufficiently to speed up the process as well as allowing greater than necessary air to remain in the large amount of sponge that these filters come with. You should see notable improvement by end of day.
Been trying to find for a while, but what is the screw length and diameter for the motor? I have been trying to find info since I've been wanting to replace it and lost the screws for it.
No dejó de decir que el filtro fluval fx4 es tremenda maquinaria,de qué vale tener un filtro de alta gama cuando los distribuidores en los Estados Unidos, de los filtro fluval se demoran una semana y días para enviarte una pequeña pieza que está bajo garantía como mi persona que llevo una semana y un día y todavía no me llega y sólo tiene 9 meses de uso piénsalo al comprar.
If the motor isnt making any noise at all (not even humming) and won't turn on.... is the motor fried? The impeller was extremely dirty I cleaned that. Haven't tried to put everything back together yet.

Hello I have a question... Does Fluval makes the specific pre-filter sponge for the FX6? I'm asking this because I have cichlids with sand substrate and I'm concerned about will it damage the impeller?
We do not however due to the water flow in the FX filter series it must flow through the surrounding foam filter inserts first and is then directed to the top media basket within which you can place a fine filtration pad, sand should not pose any risk to the impeller.
why can I not find an fx4 motor anywhere? all I run is fluval but this fx4 lasted 2 months and crapped out I'm guessing it's the motor but cannot find it anywhere close by. and all second hand stores want over 100 buck plus 45 shipping

@@mistadobalina1093 I finally did get the motor replaced. but it took MONTHS of back and forth emails with the company literally 3 or 4 months from the time I started the conversation to the time I got the motor
@@mistadobalina1093 yeah all has been well now thankfully. but I believe that. I've had another dud since then but just bought used parts to fix it. it does seem every other is crap. although my fx6 has been running with no issues for 5 years. so maybe it's just the 4s. bummer yours is noisy that would piss me off too
Can you tell me why my fx6 canister is now building up with air. Has been perfect for 18 months or more. Until I changed my tank and now every time it primes it’s releasing quite a lot of air. Intake pipe and the join to the down pipe is totally submerged so can’t be sucking air in there. Is it possible there is a very small hole in that pipe or could air be sucked in from where the pipe pushing onto the canister. If I can not get it sorted I will be trying another filter. As it’s scares the fish every time it does it
After maintaining and priming your filter it can expel air due to the air initially present in filter media, are there any air stones operating near the inlet siphon? Is this a marine or freshwater aquarium?
It’s still doing it now. no it’s not from trapped air in the sponges. I’d say it’s about half a pint to a full pint of air it releases every time it prims. It is a fresh water tank and there is no air stone or anything else to make bubbles. The joint for the inlet pipe and down pipe are fully submerged under water so can’t be sucking in there. I’m assuming it’s sucking air in from the inlet from the ball valve where it push fits onto the canister. Motor I’d of thought it would leak water out not suck air in. And the same with the lid. And if it was the outlet pipe then that would certainly leak water. I’ve stripped and cleaned all seals a few times new and makes no difference. What would you recommend my next thing to try. Wether it be replacing parts or something else. Many thanks for replying.
Hi Robert, please verify that the motor seal ring has been maintained correctly: it should be cleaned and lubricated every 3 months, and replaced on a yearly basis. You can contact our customer support team for more assistance: fluvalaquatics.com/us/contact-us/
Question: Filled cannister with 8 litres of water, started it up. Turns on, then off. Waits a minute or 2, Turns on, then off. Repeats over and over. Does this mean my motor is bad?
It is normal that the unit will cycle on and off for 2 minute periods during cycling. Is the filter presently full and running normally or is it still cycling on and off with no air being expelled?
@@fluval Hi. it was cycling on and off and no air being expelled. It seemed like the impeller/motor assembly was clogged with loose debris (o-ring had come loose). Gave it all a wash, plugged it back in and now it's working. Thank you
I had 2 FX5s back in 2012. I'm setting up a new tank and started the FX6 last night and it has a very annoying hum! My FX5s were so quiet I had to put my hand on the canister to make sure it was on. This FX6 is such a dissapointment!!!!!
@@mistadobalina1093 I could hear mine through the floor below me when I was trying to sleep. That was on two brand new units. I was %100 the impeller was clear. I will never buy this brand again, I've since returned to Eheim and couldn't be happier.
The impeller on my fx4 and seems to be stuck and I can see a little rust residue on the magnet part which I cleaned of but it still does not want to dissemble does this mean I need to replace it

Please help..i have fluval fx6 and it does drops from the point of motor ..i got out the place of motor like the video i put it again and then i had again drops ...i dont know what to do ..please answer me..
That would likely be a case of cleaning and lubricating the o ring you see in the thumbnail image. Tighten the screws using an opposing cris/cross pattern and do not over tighten.
Please help, lately my FX6 won’t start after cleaning, when I plug it in it will make some noise and soon come to a full stop. I then have to unplug and remove everything from the basket and remove the motor just like in the video, then I plug the motor in let it run dry for a couple of seconds then reassemble everything, now this may or may not work, sometimes I have to do it all over again to make it work. Know that the impeller is not dirty and looks just fine to me. On the other hand, my fx4 do not have this problem at all. I just don’t know why I have to do this to make my FX6 to work. Do I need to replace the motor unit or impeller? I just had the FX6 for about a year. This process is very time consuming and I’m getting frustrated by doing this. I’m on top of all filter media and cleaning the unit once a month, so there’s no clogged sand or dirt inside the basket, this happened about 2-3 month ago.
My name is Dee, my 306 motor isn't turning. What can i do to fix that? When take that little cover off where the fan i can hear it wanting to turn. #HELPAFELLAOUT

Where would I be able to purchase a replacement for the fx4 impeller? Does it come in an assembly kit or can I just purchase the impeller itself? I can't seem to find it anywhere online. Also I would need to replace the O ring and can't find that for the fx4 as well. Can you please provide a link to where I can get them? TY
+samnella9 I did. Nothing for fx4 impeller. I'll check the fluval website but I can never find where to actually purchase the item on there. I feel like it's always just a base for part numbers and not actual checkout.
+Fluval Aquatics hi. Yes in NYC. I'm assuming because the fx4 is very new that I won't see a lot of the accessories for it yet however I wanted to make sure I know where to go if something breaks down, especially the impeller and the O ring.
I just called fluval (on hold for 45 mins) and they directed me to usa.hagen.com, however I still CAN'T find the impeller for the fx4. Does it come as a single unit like you showed in the video or as an assembly? The fx5/6 impellers are sold out on that site as well.
well i brought a fluval FX6 the impreller has problems doesnt work like it should And I also bought a FX4 same thing the impreller isn’t working like it should
Fluval Aquatics also on the bottom o-ring? My next question is. I would like to empty my tank with the excess valve, however i can't seem to find a hose that fits. The one that comes with the pump, i can't figure out how it could/would function. Can you guide me in a direction, as to how i can use this feature?
Tommy, on any O ring in that filter that lubricant is recommended. We are not sure of what you are referring to when you say "excess valve". The filter hosing supplied is ribbed and specific to the filter, splicing in additional plumbing is not recommended. To drain you use a dedicated submersible pump and appropriate hosing long enough to reach to where a suitable drain is located.
Fluval Aquatics on the bottom of the fx6 is a red valve which can drain excess water? That is supposed to be able to be used for draining purposes? Also when doing water changes?
Tommy, sorry for the confusion, lots of question traffic to attend to today, yes the drain valve is there to empty the filter when performing maintenance and can be used to do partial water changes with. Item # 20237 utility valve hosing is the recommended tubing and can be ordered under this item number. It is included with newer production units.
Hi Jerry, it uses a 30W motor, here is a link to the FX series page that will provide you with all the information available on this line: fluvalaquatics.com/ca/fx-series/
I recently got a fx6 and it's been running for 6 days amazingly. On the 7th day I got home to realize my fx6 was making a pulsing sound and the output hose was pulsing as well making the intake tube bang on the inside of my tank. I've checked for air leaks, checked all the media trays, cleaned all my fine pads and even removed the impeller to make sure it is seated properly and free if debris. I installed everything back and got it going again and it continues to do this pulsing thing. Has anybody had this problem? This is a amazing filter and I'd love to trouble shoot it before I return it

@@fluval I sure will and then I will contact the store I got it from. PetSmart has done me wrong once more. I had to return a malfunctioning Marineland C360 that I got on sale from them. I returned that and got my fluval fx6 because it was on sale as well Upon getting the fx6 box I noticed that the temper seal looked damaged. I pointed this out to the PetSmart workers and they told me it was a new unit. I took their word for it and took it home. It sat in the box at home for a week then on the second week I installed it. I did not bother to take a close look at it when I installed it because I really thought it was a legit new unit I got. Now it's a week later and it started to malfunction as well and I decided to inspect it. Upon inspecting it I came to realize that my unit had scuffed legs that were missing the small circular pads on the bottom and the legs also look like they have been drug on a rough surface like concrete. The bottom of the motor housing also looked like it got scraped on concrete as the bottom edge and corner looked scuffed. Outside of the fx6 bucket also had some wear marks on it. I know for a damn fact that I did not cause this damage because I never took my filter outside and my living room where my tank is at is smooth hardwood floor and the restroom where I take the unit for maintenance has polished tile and my tub has a padded mat where I cleaned the unit. The location under my tank where I put my unit also has a padded rubber mat on the bottom so because of all this I know for sure this unit was sold to me damaged like this. But anyways man it just sucks that a retail store would do their customers like this by selling them a well known brand item that is used. Makes me wonder if all discounted units they sell are used.
I recently bought a used FX6 for $200 and it does the same thing - there is a swooshing noise from within the canister, and a pulsating of the output hose. It’s like the canister gets going, than gets weak than it gets going, then it gets weak, right? Im Glad to know I’m not alone, lol. You’re the first one that I came across on the internet that has described what mine is doing exactly. Did you find out what’s cause it? I’d sure love to know. What was your solution? Please keep me informed. Laterz. I guess there was a reason why the guy was getting rid of it. Worst case scenario, I just buy a new one off of Amazon.
I had the exact same thing happened with mine the pulsing was banging off the glass and drove me nuts so I returned it to Petsmart got another one a year ago and it’s been working great. I was told that it was an air lock I did everything I could think of to get air out but could never get it to stop.
@@1dilligaf I actually ended up returning that FX6 and trip out on this. Pet smart sold me a used one. Them a holes though they can get away with it. When I returned it the second one I got was packaged way differently. This second one has been working amazingly since day one. You really have to watch out when buying stuff from PetSmart. This is the 3rd time they sell me something used
Hi there, I’ve recently purchased two FX5’s both second hand, and by the sounds of it, they’ve both been sitting unused for a couple of years or more. Is there a specific maintenance check I should do before attempting to setup and start the filters please? Or would it be ok for me to inspect the motor and give it all a clean as shown in this video please? Ps also just wondering how many LPH the FX5’s are rated at filtering please? And what size aquarium you recommend to be suitable for adequate filtration for the FX5 for an aquarium with American Cichlids please (just thought I’d be specific as my fish make a above average mess lol)
Hi there! We suggest you give the filters a once-over and clean them as thoroughly as possible. If they're making some noise, it's likely the pump needs a pretty good cleaning. The pump output of the FX5 is 3,500 LPH and the filter circulation rate is 2,300 LPH. A single FX5 is rated for up to 1,500 L - in your case, since you'll be keeping larger, messier fish, their capacity will be reduced. We run two FX6 filters on a 300 gallon aquarium with large South American cichlids, and the water is crystal clear and the parameters are perfect!
My Fluval Fx6 just started leaking... Only when I turn it off during water changes. I opened up the motor and it turns out that my Bushing + O-ring is missing.. that is so strange -_-
That is strange that with a missing O ring the leak only happens when the motor is turned off. We strongly advise you get both the o ring and impeller bushing before operating your filter.
Ordered a new impeller + Bushing and o-ring Kit and installed it just now. Turns out I do have a bushing + O-ring, it was so dirty that I couldnt see it. I removed it with the metal tool provided and installed the new impeller, bushing and o-ring. The water leak is still happening. I think I might have to replace the OTHER o-ring, although it sits onto of the ridges as mentioned in the video.
If that doesnt work, I dont know what I'm gonna do. Are there any possible culprits to this leak? I'm really not trying to buy a brand new motor if the solution is something simple that I might have look passed.
Hi there, we're sorry to hear about this. FX Series canister filters are equipped with 3 year warranties, so we encourage you to contact our customer support team for assistance: fluvalaquatics.com/us/contact-us/
Kevin, please check your filter media and ensure it is clean that there are no obstructions in any of the media baskets. A thorough hose flush is recommended twice a year. You should also remove the pump and check the impeller. The magnetic impeller is a wearable item and after 3 years it would not be unusual to replace it.
I am having the same problem. I just bought a 2nd fx6 for my 125. The newer one blows water out like the other one did when it was new. I'll try the impeller this weekend when i do a tank clean up.
my fx6 stopped working after I done a routine maintenance Ie change sponges etc. After I cleaned the impeller like in this video it now working Thanks for the tip Fluval.
once again fluval Rocks,, I replaced both intake and out takes on my fx6 and the microw bubbles are goneeeeeee, and stopped leaking , also I replaced all orings and greased them, thank you fluval for all your staff help and great customer service as always.
Hi Lisa. I am also having trouble with micro bubbles. I have inspected, cleaned and lubricated all the o rings. I have cut the hoses shorter for fresh ends into the in/out. Checked the impeller.. Still micro bubbles. Did you replace the in/out hoses or the valves on the top of the pump?
I’ll probably have to do this for my fx4. I noticed maybe a month or two ago the water wasn’t running anymore. I haven’t cleaned the filter in a while so I did that but I had no idea about motor maintenance. This helped a lot and I’ll have to buy a spare impeller.
We're happy to hear the video was helpful! 😊
Do you have to drain the filter first?
Mine broke after a year
Awesome video, it totally helped me and the dishwasher sound is gone! My Fluval Fx6 is as quiet as the day I hooked it up. Thank you
We're glad to hear the video helped!
This is the problem I'm having right now with my Fx4. "Dishwasher sound" describes it perfectly. Hoping this will fix it
I have the Fx5. It was used when i purchased it, never maintananced until today which is little over a year because it started making noise. I unscrewed the motor, rinsed everything out with the waterhose, no brush needed. Put it back together, noise gone🤷♂️ No rebuild kit needed if nothing is damaged
Thank you for sharing, The benefits of regular maintenance cannot be over stated.
I tried but this repair and all the water poured out from the housing, and my fish and I were electrocuted
@@macbook802 nice joke
I have 2 or and a gold fish in the 125 gallon tank , all black filters and foam pads have been changed also, even have added new fluval media ,the propeller has also been checked and cleaned, I order a connect values, one for the intake and out tank, from fluval they will be here on the 14th,
THANK U U ARE AWESOME
Fantastic video but u need to show the dirty of the hobby by that I mean u have to get dirty as well
Do you have to drain the fx6 before taking the 4 screws out?.
Doug, absolutely, the filter should be empty before performing this type of maintenance.
Does the canister need to be drained of all the water before cleaning the impeller or can I just pull the motor off the side with water in it?
Hi there! The canister needs to be emptied in order to service the motor.
Thank U!
Hey I just fix it I dont know how I disassemble the pump and resemble it , still strong and SUPER smooth and quiet Im very happy .
At the 6:40 mark in the video we demo and explain re-installation...
Tengo un problema , no consigo la bomba del fluval FX4
Would a small leak under the motor housing be due to the motor housing O-ring or the little O-ring and bushing used within the impeller kit..?
Most likely due to the motor housing O ring. Perhaps it was misaligned after reassembly post maintenance.
Fluval Aquatics I noticed that it really started dripping when I shut off the outake valve.. Anyway I replaced the O-ring on the same day as my original comment and no problems since. Hopefully future models will have a much bigger and better seal system that can hold up and handle a lot more pressure.
I had the fx6 for a year now , i didnt know that we have to do the impeller. In my next cleaning , is it time to clean my impeller ? Or how soon to have it clean ? Thanks
Hi there! We recommend cleaning the impeller every 3 months, so we'd say you're due to clean it! You'll likely notice an improvement in filter performance once the impeller's been cleaned. 👍
How often do you clean impeller? Mines18 months and I never even looked at it😳
As the only moving part in the filter, it's important to clean and replace the impeller regularly to keep the system running as expected! We recommend cleaning the impeller assembly every 3 months and replacing it on a yearly basis.
You saved me...
So I have a question?
Me and my gf have a 125 gallon and a fx6 filter on it. She's had the filter now for a little over 4 years, well a few days ago, it started to make weird noises and then just today my gf messaged me and said that it stopped running completely.
We drained it, I took out the motor and cleaned it, put the motor back properly, refilled the filter, and now it won't start.
We are thinking of replacing the motor entirely, but I'd like input from the professionals before we make that decision.

Nice video as always. I have never done this. Is this a routine thing that needs to be done every year or so, or only if it stops working or is makes noise? I am very nervous about this as I can see 15 different things that can go wrong when I do this lol!
Don't be nervous, it's very straightforward! We recommend checking and cleaning the impeller assembly every 3 months - as the only moving piece in the filter, keeping it clean will guarantee the best filtration efficiency! Yearly replacement of the impeller assembly is recommended since the impeller spins 24/7 and does wear over time.
@@fluval Mine ran strong for 3 years, with only some difficulty getting it to prime lately. Totally missed this part of the maintenance and never cleaned it once. Will be replacing all the seals and impeller tomorrow!
Noisy Impeller, suspect the top Bushing is worn out as I can wiggle the bottom plate on the impeller. Am I right to pressume that this indicates that the top bushing is worn out?
Hi Chester, thank you for your comment. A noisy impeller can be due to the impeller itself or the impeller shaft and busing. Please contact our customer service team for further assistance with this. 😊 fluvalaquatics.com/us/contact-us/
My fx4 motor housing unit gets really hot when running . . . Is this normal or do I have a problem
It's normal for FX motors to become warm to the touch! This is actually a design choice - as a result of the pump being outside the canister, the heat it generates is not transferred to the aquarium water, helping to keep your fish safe and healthy. 👌
If the motor feels unusually hot, try giving the impeller, impeller shaft and impeller well a thorough cleaning.
Can you send me a link to where I can purchase a replacement impeller for the fx4? I still can't find one anywhere. TYIA
hi John, The FX4 is a new release so a slight delay is to be expected. Please visit www.fluvalaquatics.com and enter your country, select the contact page and reach out to us directly, we will help you locate a dealer with stock or will get back to you if the product has not yet arrived in your market.
I just ordered mine from amazon in Canada.
I assume the fx 4 is empty of water before removing the impeller.
Yes! 😎
So after a couple years my impeller died I think. Hopefully not the motor. Is that usual? Fx4 175 gallon tank.
Hi there! The impeller can't "die", as there are no electrical components to it. Since the impeller is the only moving part in the filter, it does wear over time and therefore requires periodic (yearly) replacement!
I always have a problem with the clips on the fx5 and fx6. When I loosen all the clips and hang them down ,one clip always comes out. It is a pita to put it back onto the canister.
Hi Craig, this may be a faulty fastener, the rubber base may be damaged. A replacement will be needed: FX5 Fastener, item # A20214, FX6 Fastener item # A20215.
Oops I meant to oranda goldfish they are both about 6 inches booth fx6s on the 125 get cleaned on a regular basis all pads have been changed and I'm waiting for my intake and outtake new valves to come in the ones that clip into the filter cuz the outtake Vale is dripping but when I turn the flow down on it it stops also I noticed that the microbubbles stopped when I turn the Val down on the out take tube where it was leaking so maybe it's that. I'm hoping it's that the other fx6s running fine and I got them at the same time I had an Oscar in that tank at one time that's why there's two fx6s on there as I rehomed the Oscar I ended up putting my goldfish in there just too I will be adding two more but they are in a hospital tank right now for a few weeks before I add them
My fx6 impeller is not running smooth. It spins in jerky motion, and does not generate suction. I have cleaned as shown here, as well as verifying multiple times that my inlet and outlet to the pump are clear. There are no blockages. Is there anything else I can do or is this a motor failure that requires replacement
Hi Mike, we're sorry to hear about this. The impeller may indeed be in need of replacement: as the only moving part in the filter, it's recommend to replace it on a yearly basis. We encourage you to contact our customer support team for more assistance: fluvalaquatics.com/us/contact-us
@@fluval I've ordered a fluval impeller kit already. I'm going to try that first, and if it's the motor itself that's failing and the impeller doesn't fix the issue I also ordered an aftermarket motor that fits as a replacement. I'm hoping it's just the impeller and I can return the motor, but this filter has had disappointing flow since day 1 so I wouldn't be surprised if the motor failed. Even when clean and brand new I was only getting about 450gph, with no additional media and only 2ft head height. The impeller didn't appear to have any damage or bending, but I will try a new one with a new bushing to see how that does. Thanks for the feedback.
@@fluval it was the motor itself. The impeller rotates flawlessly in my Chinese knockoff motor that just showed up. Not sure what is failing in my OEM FX6 motor, but it doesn't spin the impeller anymore. For as much as these cost, they oughta last more than 2 years. This one has been disappointing since it came out of the box. I guess a bad motor would explain why.
I have a question, I just purchased the FX4 and installed it and is up and running. The impeller and motor housing, how warm does that housing get?
Hi there! The motor of an FX Series filter will generally be warm to the touch when in use.
@@fluval thanks for the reply
so does the new bushing come with its own new o-ring, i did not see you replace the one you removed.
Hi David! The replacement impeller does indeed come with a replacement O-ring as well.
Should the impeller start and stop?
Hi Ethan! It's normal for the motor to turn itself off once every 12 hours. If you're noticing more frequent interruptions, please contact our customer support team for assistance: fluvalaquatics.com/us/contact-us/
where is the Fluval silicone sold at and how do you know the propeller needs to be replaced is it simply signs of wear on the outside or reduced flow
Hi Bobby, Fluval carries a silicone lubricant. You should be able to pick it up at your nearest PetSmart. bit.ly/2b7vzah
The FX maintenance schedule in the instruction manual provides some insight as to when you should check and replace. bit.ly/2apYXVr
I have a 38 gallon marinland bowfront tank and I'm going to put a pleco, corys, some types of tetras, and neon tetras, which fish should I add first
The fx 5 of course
+Steven Royer no I was asking which of those fish should I add first
Sorry to bother you again, just wanting to double check the flow direction in the FX5 please.
Should I place mechanical media in the bottom tray, then my bio media in the above 2 trays please?
Or bio media in the bottom 2 trays and mechanical media in the top tray please?
Sorry, I haven’t had any luck with finding out solid info.
Also wondering if there’s an online user manual available please?
Thank you once again for any feedback you can provide 😊
The flow through FX filters is as follows: the water first moves to the bottom of the canister, and then rises to the top through the foam pads. It then passes back to the bottom of the canister through the media trays in the middle, before finally being returned to the aquarium.
So, you'll want your mechanical filter media on the top tray, and your biological filter media on the bottom 2 trays.
You can find the user manual and answers to questions like this here (link is for FX6, but functionally it's the same as the FX5): fluvalaquatics.com/us/product/fx6-high-performance-canister-filter/

I have the fx4 and it attaches with only 3 screws, not the 4 that you show! Do I have an earlier model??
Hi! The FX4 only has 3 screws, it's the FX6 that has 4!
Do I have to drain my FX6 before doing this?
Hi Nick! Yes, the filter must be empty before maintaining the motor.
Great vid, thank you. Out of curiosity whats the gph on this pump and who makes the motor block for the FX6? Thank you/
Hi there! The pump output of the FX6 is 925 US GPH / 3,500 LPH. We manufacture all components of FX series canister filters. 👍
@@fluval Thanks for the quick reply. Cheers. The motor block on the this particular motor is the same as my other pumps which are marketed under different brands... I have 4 different pumps and looking at them on my desk and all the same (can interchange impeller, volute, mounting points etc between all of them and they provide different specs according to the parts and application used):
The four pumps on my desk are a Red Dragon 1000, Red Dragon 600, Askoll 1500 and a Laguna 1350 which I purchased through Hagen and all are using the same motor block made by Askoll and each pump is modified as per each vendors specifications such as mounting, bearings, volute etc.. so my question again, who makes the Motor block for this particular pump? is it Askoll based on the Askoll 1500 motor block? Fluval Aquatics does not make this motor block unless the patent was purchased from Askoll. Please advise.
@@V1ZFN in italy they seem to sell Fluval products as: Fluval by Askoll so id figure they are a fluval partner? or they own hagen or so. oh hagen owns Fluval, google Fluval aquaclear and Hagen Aquaclear.
It looks like I accidentally broke my FX4 case. Now it leaks out the bottom. The plastic case is cracked. Where can I buy a new case? I have looked on your website, you sell everything except the case. Do I have to buy a whole new filter?
They have replacements just look it up
I have a 12 plus year old FX5 that I just replaced the impeller and seals because it would stop working periodically. I cleaned the intake and output hoses as well- nothing was real dirty. The output flow still doesn't feel like the day I got it. Does that mean I need to replace the motor unit now? I have not seen any information about "if" and "when" that would be necessary.
Hi Chris, the motor head doesn't need to be replaced. Try cleaning out the other parts of the filter - it's possible the ribbed hosing needs cleaning, for example!
I have to replace the axel, twice. I fallow the instructions, and happened again !!! The kits are so expensive, and broken so often, for real, the aquarium dirt is the only way to know the filter stop. It’s no fun
My FX4 came with a red rubber cap inside the motor housing . Ive tried to research a ton but dont see anyone with the same red cap as mine does. My fx4 had issues priming everytime i clean it and service the impellar. Any way you could reach and help? Ive only had it 20 months. Thanks

Hi there, we are sorry to hear that you are having some trouble with your filter. Our first suggestion would be to refer to page 7 of the products user manual to ensure that the filter is within the constraints provided in our diagram. The distance from the top of your filter to the waterline in the aquarium should be within 20cm to 150cm and the distance from the water line to the peak of the tubing (top of the aquarium rim) should be no more than 20cm. If your filter is placed within these constraints and is still giving you some trouble, please reach out to our customer service team so that we can investigate this further with you! Below is a link to our customer service team as well as a link to the FX6 product manual, we hope this helps! 😊
I have 2 fx6s on my 125 gallon tank , I've had them both for 2 years now and replaced top cover cick fit o-ring cover ring gasket all suction cups tubing in tank and outtake adapters connects and the motor seal, cause I was getting the mico bubbles and after I did all of that it still does it , if I turn the flow down just a little on the outtake it seems to stop, also the outtake val, is dripping but it also drops once I turn the flow down, I also order 2 new ones , one for intake and out take, if this down work I am ripping the the thing off the tank,
Hi Lisa. This all depends on how often the filter is cleaned, what species of fish you keep (some are obviously dirtier than others), the quantity of fish you keep, and the size of your tank. It's also possible the foam blocks have aged and are perhaps collapsing, especially if a regimented maintenance schedule hasn't been maintained. A Severely clogged filter can be the reason too, in which case you would want to look at replacing the intake and output valves.
I'd actually recommend he buy another brand that has the game GPH, higher bio capacity, withstand user negligence and through all of this runs completely silent. German made - starts with an E.
Hi fluval. I have a fx6. It has don't great from a year and it has been running crappy. I tried cleaning it all out. I bought a new impeller and seals. To try that. I have set it all back up and now it's not doing anything. Any ideas of what could be going on?

Hi Joseph! Both the FX4 and the FX6 would be suitable for that tank size, so it ultimately depends on the tank stocking and your maintenance routine! Remember that you can never over-filter a tank, so we'd recommend the FX6. 👍

I have 2 brand new FX6 for my 140gl just put together yesterday but the water flow is very low and it do noise like I can hear the water noise. Can you help me please. Thank you.
This is likely due to air in the system and not filling the canisters sufficiently to speed up the process as well as allowing greater than necessary air to remain in the large amount of sponge that these filters come with. You should see notable improvement by end of day.
Been trying to find for a while, but what is the screw length and diameter for the motor? I have been trying to find info since I've been wanting to replace it and lost the screws for it.

Hello I have a question... Does Fluval makes the specific pre-filter sponge for the FX6? I'm asking this because I have cichlids with sand substrate and I'm concerned about will it damage the impeller?
We do not however due to the water flow in the FX filter series it must flow through the surrounding foam filter inserts first and is then directed to the top media basket within which you can place a fine filtration pad, sand should not pose any risk to the impeller.
Fluval Aquatics Thanks for the response I’m glad I had put fine pad in the top tray under the bio foam.

@@mistadobalina1093 I finally did get the motor replaced. but it took MONTHS of back and forth emails with the company literally 3 or 4 months from the time I started the conversation to the time I got the motor
@@mistadobalina1093 yeah all has been well now thankfully. but I believe that. I've had another dud since then but just bought used parts to fix it. it does seem every other is crap. although my fx6 has been running with no issues for 5 years. so maybe it's just the 4s. bummer yours is noisy that would piss me off too
Can you tell me why my fx6 canister is now building up with air. Has been perfect for 18 months or more. Until I changed my tank and now every time it primes it’s releasing quite a lot of air. Intake pipe and the join to the down pipe is totally submerged so can’t be sucking air in there. Is it possible there is a very small hole in that pipe or could air be sucked in from where the pipe pushing onto the canister. If I can not get it sorted I will be trying another filter. As it’s scares the fish every time it does it
After maintaining and priming your filter it can expel air due to the air initially present in filter media, are there any air stones operating near the inlet siphon? Is this a marine or freshwater aquarium?
It’s still doing it now. no it’s not from trapped air in the sponges. I’d say it’s about half a pint to a full pint of air it releases every time it prims. It is a fresh water tank and there is no air stone or anything else to make bubbles. The joint for the inlet pipe and down pipe are fully submerged under water so can’t be sucking in there. I’m assuming it’s sucking air in from the inlet from the ball valve where it push fits onto the canister. Motor I’d of thought it would leak water out not suck air in. And the same with the lid. And if it was the outlet pipe then that would certainly leak water. I’ve stripped and cleaned all seals a few times new and makes no difference. What would you recommend my next thing to try. Wether it be replacing parts or something else. Many thanks for replying.
Do you have to drain the fx4 first?
Yes, the filter must be drained in order for the motor to be serviced. 👍

Question: Filled cannister with 8 litres of water, started it up. Turns on, then off. Waits a minute or 2, Turns on, then off. Repeats over and over. Does this mean my motor is bad?
It is normal that the unit will cycle on and off for 2 minute periods during cycling. Is the filter presently full and running normally or is it still cycling on and off with no air being expelled?
@@fluval Hi. it was cycling on and off and no air being expelled. It seemed like the impeller/motor assembly was clogged with loose debris (o-ring had come loose). Gave it all a wash, plugged it back in and now it's working. Thank you

I had 2 FX5s back in 2012. I'm setting up a new tank and started the FX6 last night and it has a very annoying hum!

That would likely be a case of cleaning and lubricating the o ring you see in the thumbnail image. Tighten the screws using an opposing cris/cross pattern and do not over tighten.
@@fluval thank you very much..i changed the black rubber ..it was harder than the new one..i cleaned there and now all ok..!!:))
Please help, lately my FX6 won’t start after cleaning, when I plug it in it will make some noise and soon come to a full stop. I then have to unplug and remove everything from the basket and remove the motor just like in the video, then I plug the motor in let it run dry for a couple of seconds then reassemble everything, now this may or may not work, sometimes I have to do it all over again to make it work. Know that the impeller is not dirty and looks just fine to me. On the other hand, my fx4 do not have this problem at all. I just don’t know why I have to do this to make my FX6 to work. Do I need to replace the motor unit or impeller? I just had the FX6 for about a year. This process is very time consuming and I’m getting frustrated by doing this. I’m on top of all filter media and cleaning the unit once a month, so there’s no clogged sand or dirt inside the basket, this happened about 2-3 month ago.
Hi Frank, how are you priming the FX 6 before starting it after maintenance? What is distance from water surface to top rim of aquarium?
Fluval Aquatics it suppose to self prime after plug it in correct? The distance is about 1-1.5 inch. My fx4 is working fine in the same tank btw.
hi how ofen i need cleen motor i hawe sand substrate in akvarium, or send will not harm the motor?
As regular maintenance the FX motor can be serviced at once a year, remove, clean, lubricate.
My fx4 ceramic shaft im broken drop to floor. And now i have problem but i cant buy separate. How can you help me Fluval?
If the ceramic shaft has broken, you'll need to purchase a new Magnetic Impeller Assembly (item A20208).

hey i was wondering what happend to the betta babies of the bettas spawning that you posted 2 years ago
Hi, do you mean this one? ua-cam.com/video/742a0_JsaSY/v-deo.html
How often we need to clean impeller and motor assembly?
One to two times a year depending on fish stocking density.
Fluval Aquatics thank you!
My FX5 pump make electrical noise It annoying. after second clean up but it work well
The noise is likely a mechanical one, did you replace the bushings, that would a good first step.
I simply rinsed all the dirt out of mine with water hose. Noise gone. Quiet as a mouse. No kit was needed.
My name is Dee, my 306 motor isn't turning. What can i do to fix that? When take that little cover off where the fan i can hear it wanting to turn. #HELPAFELLAOUT

Where would I be able to purchase a replacement for the fx4 impeller? Does it come in an assembly kit or can I just purchase the impeller itself? I can't seem to find it anywhere online.
Also I would need to replace the O ring and can't find that for the fx4 as well. Can you please provide a link to where I can get them? TY
Try ebay or amazon or fluval itself.
+samnella9 I did. Nothing for fx4 impeller. I'll check the fluval website but I can never find where to actually purchase the item on there. I feel like it's always just a base for part numbers and not actual checkout.
Hi john, are you in the US?
+Fluval Aquatics hi. Yes in NYC. I'm assuming because the fx4 is very new that I won't see a lot of the accessories for it yet however I wanted to make sure I know where to go if something breaks down, especially the impeller and the O ring.
I just called fluval (on hold for 45 mins) and they directed me to usa.hagen.com, however I still CAN'T find the impeller for the fx4. Does it come as a single unit like you showed in the video or as an assembly? The fx5/6 impellers are sold out on that site as well.
well i brought a fluval FX6 the impreller has problems doesnt work like it should And I also bought a FX4 same thing the impreller isn’t working like it should

Hello fluval. So i am wondering, should i / can i apply silicone oil on the BOTTOM o-ring in the motor house?
Tommy, you should use Fluval lubricant item # A325.
Fluval Aquatics also on the bottom o-ring? My next question is. I would like to empty my tank with the excess valve, however i can't seem to find a hose that fits. The one that comes with the pump, i can't figure out how it could/would function. Can you guide me in a direction, as to how i can use this feature?
Tommy, on any O ring in that filter that lubricant is recommended. We are not sure of what you are referring to when you say "excess valve". The filter hosing supplied is ribbed and specific to the filter, splicing in additional plumbing is not recommended. To drain you use a dedicated submersible pump and appropriate hosing long enough to reach to where a suitable drain is located.
Fluval Aquatics on the bottom of the fx6 is a red valve which can drain excess water? That is supposed to be able to be used for draining purposes? Also when doing water changes?
Tommy, sorry for the confusion, lots of question traffic to attend to today, yes the drain valve is there to empty the filter when performing maintenance and can be used to do partial water changes with. Item # 20237 utility valve hosing is the recommended tubing and can be ordered under this item number. It is included with newer production units.

What is the part number for that o ring ?
Hello, available part numbers can be found here: fluvalaquatics.com/manuals/fxseriesinstructionmanual.pdf
is there a version of this FX6 that has a wattage of 110v-240v?
Hi Angelo, no there is not, they are two separate versions.
@@fluval can you refer me to that version that has that wattage? thank you very much
Can you place the input next to a sponge filter
As long as the intake does not inhale any air being used to drive the sponge filter, we see no issues.
The air on my sponge filter is being pushed to the surface

Can I put de fluval fx 6 in a 110 gallón aquariun?
Absolutely, if you have fish that enjoy current and have a need for stronger filtration it would be suitable to do so.
I need a new Fx4 fan but I went on Amazon and on the Internet I can't find nothing

How many watts is the fx4?
Hi Jerry, it uses a 30W motor, here is a link to the FX series page that will provide you with all the information available on this line: fluvalaquatics.com/ca/fx-series/
I recently got a fx6 and it's been running for 6 days amazingly. On the 7th day I got home to realize my fx6 was making a pulsing sound and the output hose was pulsing as well making the intake tube bang on the inside of my tank. I've checked for air leaks, checked all the media trays, cleaned all my fine pads and even removed the impeller to make sure it is seated properly and free if debris. I installed everything back and got it going again and it continues to do this pulsing thing. Has anybody had this problem? This is a amazing filter and I'd love to trouble shoot it before I return it
Hi Eddie, we're sorry to hear about this! We encourage you to contact our customer support team about this matter, they'll be happy to help you: fluvalaquatics.com/us/contact-us/
@@fluval I sure will and then I will contact the store I got it from. PetSmart has done me wrong once more. I had to return a malfunctioning Marineland C360 that I got on sale from them. I returned that and got my fluval fx6 because it was on sale as well Upon getting the fx6 box I noticed that the temper seal looked damaged. I pointed this out to the PetSmart workers and they told me it was a new unit. I took their word for it and took it home. It sat in the box at home for a week then on the second week I installed it. I did not bother to take a close look at it when I installed it because I really thought it was a legit new unit I got. Now it's a week later and it started to malfunction as well and I decided to inspect it. Upon inspecting it I came to realize that my unit had scuffed legs that were missing the small circular pads on the bottom and the legs also look like they have been drug on a rough surface like concrete. The bottom of the motor housing also looked like it got scraped on concrete as the bottom edge and corner looked scuffed. Outside of the fx6 bucket also had some wear marks on it. I know for a damn fact that I did not cause this damage because I never took my filter outside and my living room where my tank is at is smooth hardwood floor and the restroom where I take the unit for maintenance has polished tile and my tub has a padded mat where I cleaned the unit. The location under my tank where I put my unit also has a padded rubber mat on the bottom so because of all this I know for sure this unit was sold to me damaged like this.
But anyways man it just sucks that a retail store would do their customers like this by selling them a well known brand item that is used. Makes me wonder if all discounted units they sell are used.
I recently bought a used FX6 for $200 and it does the same thing - there is a swooshing noise from within the canister, and a pulsating of the output hose. It’s like the canister gets going, than gets weak than it gets going, then it gets weak, right? Im Glad to know I’m not alone, lol. You’re the first one that I came across on the internet that has described what mine is doing exactly. Did you find out what’s cause it? I’d sure love to know. What was your solution? Please keep me informed. Laterz. I guess there was a reason why the guy was getting rid of it. Worst case scenario, I just buy a new one off of Amazon.
I had the exact same thing happened with mine the pulsing was banging off the glass and drove me nuts so I returned it to Petsmart got another one a year ago and it’s been working great. I was told that it was an air lock I did everything I could think of to get air out but could never get it to stop.
@@1dilligaf I actually ended up returning that FX6 and trip out on this. Pet smart sold me a used one. Them a holes though they can get away with it. When I returned it the second one I got was packaged way differently. This second one has been working amazingly since day one. You really have to watch out when buying stuff from PetSmart. This is the 3rd time they sell me something used
right on time had a leaked on mine and had to figure out where the o ring went and that what it was O ring was not put in the right place
Awesome, Dwain! Glad the video helped.
What happened to the FX5 ?
It was replaced by the FX 6 two years ago.
Hi there, I’ve recently purchased two FX5’s both second hand, and by the sounds of it, they’ve both been sitting unused for a couple of years or more.
Is there a specific maintenance check I should do before attempting to setup and start the filters please?
Or would it be ok for me to inspect the motor and give it all a clean as shown in this video please?
Ps also just wondering how many LPH the FX5’s are rated at filtering please?
And what size aquarium you recommend to be suitable for adequate filtration for the FX5 for an aquarium with American Cichlids please (just thought I’d be specific as my fish make a above average mess lol)
Hi there! We suggest you give the filters a once-over and clean them as thoroughly as possible. If they're making some noise, it's likely the pump needs a pretty good cleaning. The pump output of the FX5 is 3,500 LPH and the filter circulation rate is 2,300 LPH. A single FX5 is rated for up to 1,500 L - in your case, since you'll be keeping larger, messier fish, their capacity will be reduced. We run two FX6 filters on a 300 gallon aquarium with large South American cichlids, and the water is crystal clear and the parameters are perfect!
@@fluval awesome, it’s rare to see support like you are obviously providing in a brilliant way.
I appreciate your help. Thank you ✌️
My Fluval Fx6 just started leaking... Only when I turn it off during water changes. I opened up the motor and it turns out that my Bushing + O-ring is missing.. that is so strange -_-
That is strange that with a missing O ring the leak only happens when the motor is turned off. We strongly advise you get both the o ring and impeller bushing before operating your filter.
Ordered a new impeller + Bushing and o-ring Kit and installed it just now. Turns out I do have a bushing + O-ring, it was so dirty that I couldnt see it. I removed it with the metal tool provided and installed the new impeller, bushing and o-ring. The water leak is still happening. I think I might have to replace the OTHER o-ring, although it sits onto of the ridges as mentioned in the video.
If that doesnt work, I dont know what I'm gonna do. Are there any possible culprits to this leak? I'm really not trying to buy a brand new motor if the solution is something simple that I might have look passed.
sorry, one more question. Are the fluval fx5 and the fluval fx6 motor seal rings identical?
Positioning the O ring properly is all that should be necessary, a new motor is not required in this instance.
can u send me a link for the fx6 one
Allen, absolutely, here you go: www.fluvalaquatics.com/ca/product/A219-fx6-high-performance-canister-filter/#.WV5NMRUrLcs
mine stopped working in less than a year. Doesn't give me a lot of positive thoughts about the quality.

Is there a torque rating on the screws?
No there is not however as this is plastic ensure a firm tightening but do not over tighten.
Hey guys I want to know what is the best food for bala shark?
I brought it 3 years ago. The water comes out is weak now. 🤣 Is it too old or I did not do it right way ?
Kevin, please check your filter media and ensure it is clean that there are no obstructions in any of the media baskets. A thorough hose flush is recommended twice a year. You should also remove the pump and check the impeller. The magnetic impeller is a wearable item and after 3 years it would not be unusual to replace it.
Fluval Aquatics I will. Thank you so much.
I am having the same problem. I just bought a 2nd fx6 for my 125. The newer one blows water out like the other one did when it was new. I'll try the impeller this weekend when i do a tank clean up.
