Biohome filter media supports both aerobic and anaerobic bacteria so is able to process ammonia, nitrite AND nitrate.
The gel filter starter balls speed up the development of a bacterial colony on / in filter media by slowly releasing live bacteria as they dissolve over a 1-2 week period.

Great video again, we live in Indonesia and have made moving beds from 2ltr bottle with cut up drinking staws and a few marbles at the bottom, saved our fish recently when pump failed for weeks:-)
Very thorough video Richard, well done. Thanks for the links! I think im going to set up a dye filled media tower and just keep in on my desk hahah, its cool to watch!
DIY AQUAPROS No worries, man. I see you're going from strength to strength and that's great. Thanks for watching and appreciating the video.
A great couple of fishy vlogs you've treated us to this week.Very informative and well thought out and couldn't have come at a better time.
Cheers!
steve lewis No worries, it had been a long time since I had done any fish / filter related videos and there will be more to come over the coming months.
Thanks for the video, I began using the biomotion spheres for almost 6 months in my moving bed filter, not near the amount of motion you are showing, more friction to decrease the spheres from breaking. I have had excellent results and love the product but was already a fan since I use the biohome in my cannister filter. Keep up the great work. Thanks
I had the pump turned up way too much in this video and it is definitely best to either get the biomotion going in a cyclical motion of have minimal movement as you say Glad it is working well for you as it has way more surface area than any plastic media ever could.
I learn so much from your channel it's not funny!
I only graduated to canister filtration this year and you had the best "plain language" explanation as well as demonstration of how to set one up. Now I've learned something else... I have never (honestly!) seen a moving bed filter like this even after having worked in a pet shop decades ago.
Granted - undergravel filters were 'top of the line' back then but still... this idea is so simple and I can immediately see how effective it would be. Amazing the amount of agitation in that filter with such a low volume of air driving the system! This can be done for the cost of a cheap air pump, some hose and a 2-liter bottle from the trashcan! Plastic media can be bought or made from pvc and plastic scraps. Simply a wonderful, and in retrospect, obvious way to help keep a tank's water darn near perfect!
Moving beds look cool and they do a great job of stripping out ammonia and nitrite too. Glad you like the idea and appreciate the videos as I love making them.
Great video pond guru, I learned a lot of things about moving bed filters that I didn't know before. You have a very educational youtube channel and I have learned so much from you and for that I would like to say thank you.
No worries, I love to put out helpful videos whenever I can and will be uploading another aquarium related video this weekend with any luck.
This video has been really informative! I have been toying with the idea of and overhead sump made from a 3ft window planter but was undecided on what media to use, after watching this I do believe I shall be using biomotion for bother the moving bed and static bed sections of the sump, so thank you very much for this video :)
No worries - glad you enjoyed the video. The one I did around the same time about the nitrogen cycle and filter media would probably have been more use for an overhead filter as the best media choice for that would be either biohome mini ultra or the biohome ultimate (both use static). Here is the link: ua-cam.com/video/-O2SCXDO2RI/v-deo.html
I have been keeping fish since I was a child (mom told me about having a fish tank even in my nursery that my uncle setup and would bring a bag of fish when he would visit) even worked in a pet shop running their fresh, brackish and saltwater when I was a young man so I can say that your ideas regarding filtration design is just amazing. Your simple DIY projects are outstanding in their functionality and no doubt outperform some of the best brands. Thanks for sharing them with us. *** I am trying to get hold of the Biohome Plus Media (since it is the smallest) and Filter Starter Balls for a HOB Aquarclear 70. Mr Chamberlain has prompt and helpful but he is awaiting another shipment of the Biohome Plus Media .
+Walter Crews Dear Walter,
Thanks for the comment and I'm glad you enjoy the videos.
If Don is out of the biohome plus you could try the biogravel as it fits into the HOB filters extremely well and will offer the most available surface area per volume because of its small size.
You would need a fine mesh bag to put it in like this type (but maybe smaller): www.amazon.co.uk/20pcs-Drawstring-Filter-Aquarium-Garden/dp/B016W7HL3I/ref=sr_1_1?ie=UTF8&qid=1462171454&sr=8-1&keywords=aquarium+filter+bag
The shipping from UK to US can be prohibitive due to the media weight and shipping charges.
Hope that helps.
Regards,
Richard
Haha, nice explanation of the moving bed filter. My mbf is just the same as yours so i don't need to post it. 3am here in Singapore, still can't sleep. Keep up the good work!
DIY Aquarium Filters You're up even later than me I tend to go to bed around 12 so I hope you finally got to bed and it was static, not moving, lol
hello.. thanks to your shared knowledge about moving bed media. actually it was your shared knowledge that i got started to koi pond. but sad to say i lost all kois last year when typhoon haiyan (yulanda) hit my town.
maybe next year i'll fix the pond after the house is 100% fix.
more power to your channel. =]
subzerized sub Typhoons are something we don't have to worry about in the UK, just wet miserable weather for most of the year, lol.Hope you get your house and pond fixed up soon and thanks for watching and appreciating the videos.
Great video as usual Richard. I received some of the bio home balls and some of the big big bio home today. Haven't decided where to put them as my moving bed with K1 is just starting to mature. I guess that could be a good excuse to tell the budget keeper why I need another tank. LOL
Thank you sir
Bob from Milwaukee USA
Just out them anywhere in the filter and they will seed all the media with good bacteria. If they are in with K1 they will help to build up a bacterial layer on the media allowing it to move more freely through the water.

Pondguru How would compare these media to fluidized sand?
I was just going to make one of these but I don't want higher nitrates. Why does this produce Nitrates? Do all moving bed filters bring up the nitrates?
I've got mine in the wrong order on my pond then , that's probably why my nitrates are higher than I'd like . That's my next job swap the bays around. Thanks Richard 👍
PG...great vid. lots of info. I wish I could buy K1 micro in different colors
Greetings from Finland and thank you for your lovely videos, I came back and back again to watch them to get knowledge from filters. I have been planning to set up an external moving bed filter (in a cannister, not a sump) and connect the outflow to aquaponic trickle filter. I want to raise some houseplants above the aquarium, maybe someday turn it to vivarium! Would it work, to connect the moving bed filter to aquaponics? What would happen to nitrites? What media would work the best in this setup?
Greeting Pondguru, I really love your videos regarding tips and advice. I had a question about the moving bed filter. Since the container are transparent, and Light's UV keep expose into the media too. Does UV affected growing of the beneficial bacteria? Thanks.
Replaced my K1 with K+. Done some mods to my filter (vortex) with stronger custom strainers, a tricky mod, a lot of work but well worth it. It will handle 150 liters of media.
Iam emailing u let u know I have built the moving bed filter it's been almost a week. and the 90 % of the k1 micro media has started to move in a clock wise motion . So as u told us this filter will help in the spikes of bacteria and nitrates so iam hopeful this will help me . In my tanks iam trying it in my 29 gallon tank . So again u are my hero and thanks from all the ones who don't know these things as you do. Thanks pond guru guy
Great I'm glad that it is starting to move properly. Once it has moved well for a couple of weeks try moving the air inlet so air travels up the middle of the filter and the media will move in a more chaotic way. It will bash together more that way and be more effective.
Glad you enjoy the videos as I love making them - just wish I got more time for filming.
Thanks again ive added the bacteria balls and moved the air to the middle of the bottle its moving a little slow if u think its better to speed it up I can the air flow I mean
It will move faster as the media matures so I would personally leave it but if you want to get it moving faster and can turn up the air pump then go for it. As it matures you can reduce the air flow.
Thanks for your informative tutorial
No worries, man. I love making videos which help viewers and the aquatic ones give me a great opportunity to do that as there is so much bad advice out there from 'experts'.
Look out for my next detecting video going live at 1900GMT today as it has me going out with duellin' detectors again to great effect - loved putting that one together as it was a very productive hunt.
When will you be getting out again? Miss your videos but maybe you're under 4 feet of snow now? We will no doubt be getting that dumped on us when it heads across the Atlantic, lol
not from me you wont hear it i find its very interesting and more fish keepers
should watch this excellent video richard and excellent tutorial keep up
making these videos
Andy Coakes Will do, man. I like making the educational videos and try to put as much information in there as I can so thanks for appreciating the videos.
You suggested the k1 micro medium in the filter. I have ordered it and will assemble the filter as you shown . Hopefully this filter will help in the ammonia and ph spikes thanks for your help and time to make the video .
If the pH problems are linked to ammonia (which they commonly are) then getting the ammonia under control will definitely help the all round situation.
I ordered some k1 micro from your site. will give this a go :)
Best of luck with that and thanks for the order.
Can you put bio home in with k1/helx13 and do complete cycle in one camber on koi pond? Or is it absolutely necessary to have it in a static bed / baki shower after an Oase combi bio L filter? 👍🏻
Very old video I remember it wisely. I've just made 5Litre K1 filter in my 1000L vat. Would like a tempest filter but don't understand if can run it off standard pipe or can only be adapted to a certain filter. I still think you should make your own moving bed filter and retail it
Awesome video! Best explanation and thorough. If you haven't yet made videos on protein skimmers and rotational drum filters would you please consider these in future. Also great to see you answering all the comments, I'll be placing my order if you can ship to South Africa.
I don't get involved with protein skimmers or drum filters so I don't know anything much about them unfortunately. I do ship to S. Africa but only through tracked international courier. If you let me know what you are after I can get you a price no worries.
pondguru@btinternet.com
Thanks for your reply, I'm looking for K1 micro media, about 0,4 cubic meters volume of media. I live in Johannesburg.
Andries Nortje Aaarrgh.....delivery to South Africa is a crazy price - £750 as I can't find a pallet carrier who delivers to S Africa. That is with international carrier by air (3-4 day service) and although quick is very expensive. 400 litres of K1 micro media would be £720 so that would take total to £1470 delivered which is a rare old chunk of cash. Doable but very expensive.
What if you have an average home fish tank , 20g to 55g with undergravel filters.
Can you add bio media to the up lift tubes ?
What did you say needed to be used to get rid of nitrates , that was in the moving filters ?
Thank you !!
thanks a lot for the reply
PLEASE TELL ME, AS SILICA SAND HAS LARGE SURFACE AREA , CAN THIS SAND BE USED INSTEAD OF K1 OR BIO BALLS AS MEDIA IN THE BIOREACTOR? will it provide the nitrification....
Hello, what material do you put in the moving bed, and what is its importance and benefit, and is there an alternative to it if it is not available in my country, thank you teacher
Thanks for the interesting video. I am definitely considering using a moving bed filter in a plant aquarium that I will build soon. I have a few questions about how to adjust the size of the filter or the number of filters to the size of the aquarium and also the amount of necessary media. I am planning an aquarium of about 350 liters, 2 pairs of discus, and two pairs of angel fish. And another group of small fish.Thank you.l am going to it diy way.I am going to use 2 liters plastic bottles.
(my other channel) A moving bed really only processes ammonia and nitrite and it produces a nation of nitrate. That's good for the plants and as long as you have plenty of plants the water should be fine. Ideally you'd aim for 1 litre of moving bed media per 100 litres but a moving bed is only part of a filter system. If you can add more then it's all good.
PondGuru
is my filter media arrangements correct in my 2 filter tanks system?
Tank 1
.. water from fish tank drops on sponge filters then into
.. bioballs with air injection in
bioballs are moving.
Tank 2
water from Tank 1 trickle down to K1 filters with air injection
the water is then goes back to fish tank
Very nice video. I keep goldfish so my system is on a much smaller scale as funds are limited.. I want to make a small moving bed filter. I have a 6000 liter pond. I have purchase some Hel-x and a small container that will be part of the filter system. What percentage of the filter media hel'-x do I fill the container? Is it about 50%? Can you please help.as nobody has been able to give me an answer.
What is your opinion on pot scrubbers as media in a canister filter? I see them more and more being used. Thanks for all your videos, i have a lot to watch!
They are as good as foams, ceramic rings and other material where all the surface area is external and will easily hold enough aerobc bacteria to ensure that ammonia and nitrite is processed (as long as the filter is large enough / enough 'media' is used) - however, a good lava rock would be better as far as surface area goes if you're looking for a DIY option for filter media.
Is there an equation of efficiency for K1 Micro v Static media for ammonia and nitrite removal. Most quote 1kg of static media per 100litres. Is there a K1 Micro equivalent? 🙂
Any chance of a diagram or drawing of how the koi place filter works
i have used cut straws for this and it worked,definitely not as good as the real deal k1 etc you mentioned but cheap
Cool vid man thnx
Hello sir, how are you? I want to know ---white colour of particales are made from? ??
I love this 16:45 commercial. Only thing he left out was, "But wait there's more"... about to do one for 150 gallon tank. Idk how media I would need.
I am so glad I watched this before I bought the K1! I was getting the stuff together to make one of these. The last thing I need is more Nitrates and more water changes.
Why does this produce nitrates?
Plastic media of any type in motion or not lacks the structure necessary for supporting anything other than aerobic strains of bacteria, therefore the moving beds tend to be good for the aerobic side reducing ammonia and nitrite but the end product of that process is nitrate.
Ideally you would have a moving bed followed by a static bed of good media like biohome ultra / maxi ultimate if you were using it in a sump or if it was a pond situation the moving bed outlet would go to a static bed box or shower filter filled with 30mm-50mm white pumice, biohome ultra / maxi ultimate or the new shower media we're making which packs in really nicely for a shower filter.
Thank you for getting back to me. This is for a tank that I am not sure will even have fish in it. The tank is a floating plant tank only so I can sell the plants but, I have tried this before and the plants always die. I have an established fish tank where they plants start out and they do very well in there. I wanted to transfer the plants once they get some good roots. I was told that I probably do not have enough nitrates for the plants to feed on and that I may have to get some fish or feed the empty tank. I am not going to feed an empty tank so I might have to put fish in it. Because of this, I want the tank cycled. I was going to do this DIY with the Kaldness media and have a spong in that plant tank.
Pondguru, I live in an apartment, I can't do a shower filter here. The water is on one side of the apartment and the tank is on the other.
Pondguru, so are you suggesting that I need to use another filter with media in it along with the moving bed filter?
Pondguru Loved this video, as I do all your others. I have a question, which media would you advise for use in a Discus Tank? Also, would my HOB filter (Rammed pack with Ceramic Bio rings) be considered a static filter? I would love to hear your thoughts on this, I just want the best for my discus and their tank mates. Great video with loads of great information, well done my friend.
Maurice McComie A HOB filter with ceramic rings is definitely a static bed filter as the ceramic rings are way too heavy to move unless you have crazy amount of air injected then they will smash to pieces. The biohome mini ultra or ultimate medias will outperform even the best ceramic rings many times over but a HOB isn't perfect for altering since it relies on cartridge system. An external filter is way better for a large tank which I'm assuming you have as you keep discus.
Pondguru thanks for the response. I'll definitely have a look at improving my filtration. I have 2 whisper 60 hobs on my tank with ceramics and in addition I have 3 large sponge filters that I've fit ceramics into the outlet, so all the air from the sponge filters flow over those ceramics. The ceramics in the hob just get the steady flow of water over them. It's worked well for me so far, but I'm looking for an upgrade.
Maurice McComie Most filtration issues begin and end with the media so that's the best place to start. As long as good media is well protected by layered foams and a fine particle pad / floss it will be sweet.
Pondguru Thank you so much for your knowledge and insight. You really are The Guru :D
Maurice McComie No worries, any time.
Can we put this K1 media inside the canister filter?
i would like to do an external moving bed filter
i was about to order enough K1 to fill my 55 gallon barrel moving bed filter to run my fishroom, i'm not too keen on ceramic or glass media as they seem to get clogged quickly, so would you recommend K1, K1 Micro, or Hel-x for most surface area for my money?
***** K1 micro has easily the most surface area per volume of those three plastic media so would be my choice every time. It allows for the most fluid bed too so ultimately won't need as much air to drive it.
Pondguru thanks!
Great work @Pondguru
I have a question though, since I have no access to K1, Bioglass, or similar media alternatives, and I'm really looking into setting up a moving bed filter for my 127 Lt. Tank, do you thing that something like wall screw plastic anchors, cut in pieces maybe, would make an effective alternative?
It has a decent surface area and it does float.
Looking forward for your advice.
Waleed Janabi I suppose any plastic would do to a point but it needs to be tank safe. The K1 micro is the best media and I ship worldwide (although some countries are blocked on ebay due to terrible delivery times or items going missing).
Hello, great videos. Can you please let me know which filter media you would suggest for a small external canister filter for tropical fish? Thank you.
Either biohome mini ultra of ultimate - definitely two best choices for externals Check video description for 'how to' video on external filter.
Your awesome I wish I can meet you but I live in Duluth MN in the United States. I do have question about it is this media good for a planted tank. If so I'm going to put it in my sump. I'll be running co2 too.
Making a moving bed is a decent idea for a planted tank as they only do half the biological job - they are all anaerobic so you get good processing of ammonia and nitrite and plenty of nitrate produced with no anaerobic process to remove that (so it is food for plants),
was wondering about shower filter,,, with the water trickling down wouldn't there be plenty of oxygen surrounding the biohome filter .. ? how would the Anaerobic bacteria grow there ,, thanks , luv your video.
D. Aware The structure of biohome allows for anaerobic zones even in a heavy oxygenated flow so it does great in shower systems. The larger forms of media do best in really heavy flow but smaller ones like mini ultra and ultimate do fine in moderate flow.
Can I use this type of media with a Whisper 60 HOB or Odyssea CFS 130 in my 60G planted tank? Also what do you mean by "Static Environment"? Thanks for helping out this new guy with your great videos & Greatwave Engineering since I'm in California.
Static environment refers to media which does not move. Not sure you could get a moving bed filter going in either of those filters so best to use good quality static media e.g. biohome
kaldness micro in a small water bottle for a 20 gallom tank with 4 fancy goldfish. Will the nitrates kill my fish?
Richard can i trust this Moving bed filter with my expensive Asian arowana ???
Hi Pond Guru, I have a question about this video. When you show the blue dyed moving bed filter, and the speed at witch it moves, you tell everybody that it goes befor a static bed filter. Thus the nitrates produced by the moving bed, are handled in the next static chamber. Now I have a 2 chamber filter, with pre vortex. And I have the first chamber static, and the second ( last ) chamber is K1 and K1 micro. About 50 liters with a airflow of about 2000 liters/hour or 500 gallons. It works great, but if I hear you correctly it should be reversed for better biological filtration ? Thanks for all the great vids, regards from Holland :) ( 2500 gallon pond )
Ps my static filter holds glafoam, carbon, alfagrog and matala mats
For those who don't want filters inside the tank or like bubble noise, could the same be achieved using a small external canister filter with all the trays removed and just filled with fluid bed media?
And stuck on your canister filter pump
I shoulda paid more attn when I was plumbing in the sewer plant and had to go through precaunary hep b innoculations, again thnx man
lol, no worries and I'm glad you found the video useful.
Hi pondguru. I am using filter matala biostep 10 for my 800 gallons koi pond .
My PH always go back to 4-5
I have to add baking soda to bring the ph up..
Also ammonia level always high . I think I have had an algae crash. I have added beneficial bacteria but it has taken too long to establish.
How do I keep PH and Ammonia level at stable? Thank you
I'm not sure why the pH would be so low and it sounds like the filter is too small for the pond / stock if ammonia is always high since ammonia is quite an easy one to keep down. Is that the only filter on the pond? Feel free to send pictures / videos to sales@filterpro.co.uk and I will try to help of if you're in UK just ring on 07772848730
Regards,
Richard
Do you have to use air to tumble the media or can you just use water pumps? Thanks for the nice video
It is best to use air as the system relies on a highly oxygenated environment to work well. However aquarium water pumps will often have a venturi fitted on the outlet which allows them to drag air in and spit out a water / air mix which works fine to drive a moving bed filter.
hi pondguru
think about to do this in a rise pond with a big container could I have the air switching on&off say on for 2hours a time in the day &maybe switch off all night would this be ok I have other filter running from bottom drain thanks keep up the good work
A moving bed needs to run 24/7 to be effective and having it coming on and off may seriously mess with the oxygen / CO2 balance in the water which would be no good for the fish.
Can this be used along with a canister filter or would that be unnecessary ? btw I am new to the hobby and love your videos!
If you have a canister filter of suitable size which is set up properly that will provide enough filtration so you won't need any other filter. This video shows how to properly set up a canister filter: ua-cam.com/video/lsAmSD3wVbg/v-deo.html
Hi would one of these work in a cold water tank? I have a external filter set up but find that the water gets a little dirty when the warmer weather starts to come.
Yes works in any tank but it is for biological filtration, not mechanical filtration. Could be your external is set up wrong - check out this video: ua-cam.com/video/lsAmSD3wVbg/v-deo.html
Hello.. I have just added some of the K1 media to my Bubble Magus BM 80, But I'm unable to get it to tumble, it just sits at the top half of the tube. Could it be because there are no holes in the bottom of the unit, just the hole for the water inflow.
As the media builds up a bio-film it will start to move but may take a week or two in that set up.
So how can you deal effectively with nitrates in your tank with a moving bed bottle filter, could you use two bottles one either end of the tank, one moving bed bottle filter & one static bottle filter?
+Allen Kemmett Plastic filter media does not have a suitable structure or porosity for supporting anaerobic bacteria so it would be no good for nitrate reduction. The information on my website explains more about anaerobic bacteria and how media which supports it can help reduce nitrates: filterpro.co.uk/qa-24-w.asp
hey buddy long time no talk I was just wondering where I can order your bio Home Ultra media for my fx5 also what do you think about using lava rock obviously it's not as good as the bio home but I am on a budget I was thinking to do and one tray with the bio home and second tray with the lava rock
If you can get 25mm alfagrog it may be better than the red/brown lava rock as much of the internal structure in the lava rock can be inaccessible.
I sell the biohome media on my website here: www.filterpro.co.uk and the best types for external filters are the mini ultra and ultimate. Each tray will take around 1.5kg.
Want more efficiency? Do not use the (expensive) commercial media. Use fine sand instead; the overal surface capable of holding bacteria is much larger.
i was using hydroleca plant pot soil topper i was
making them 20 years ago
Andy Coakes Before I discovered K1 that's what I was doing too, lol
Is that the little clay balls?
Dear Richard,
Thank you a lot for your videos and i bought Hel-X from you, i setup my moving bed filter following your instructions but the problem is that one month has already passed and they are not moving, they are just on top of the bottle. Can you pls tell me why? what do i make wrong?
Paolo Romantini Maybe there is too much in the restricted space or the air injection needs to be moved to one side to get the media moving. Definitely worth moving the inlet to one side of the container and getting a cycling motion going. The hel-x should operate at about a 50% fill but often needs the air up one side as it is larger than K1 and huge compared to K1 micro. Larger media is more difficult to get moving right in small spaces.
I moved the airline to one side and now it works. I just would like to ask you another question, how much strong should be the airpump? i mean assuming a 1,5 litre bottle i'm currently using a 2.6L per minute airpump.
Paolo Romantini That is easily big enough and you will find that as the weeks go on the media will move much easier.
what the diffrent between a moving bed filter and a VIBRATING BED filter. and how do you make a vibrating bed filter
They are made exactly the same just a 'vibrating bed' filter has way more media in the container so it can't rise and fall like it does in an ordinary moving bed.
I know it's kind of late to be asking a question on this subject, but does the surface texture of the media have an effect on how well the bacteria cling to it? Does rough media get colonized faster than smooth media?
To some degree yes, plastic is a very hostile environment for bacteria no matter what shape it takes and generally is not rough.
Can I slowly add bio motion with my K1 and remove my k1 as I add the bio motion .
Yes that would work, no worries
Where do
I get the bio motion from
Could you put a moving bed on the output of a powerhead filter or does it need to be air driven?
Yes you could do that, however the flow rate cannot be as fast ad most powerheads unless you are using a very large bottle/container, otherwise the water will pass over the media to quickly to colonize on the media
Do you have a video about using sand in a moving bed filter or chamber of a sump? Would love to hear your take on using sand. Thanks and your videos are very informative.
Sand seems to be a very good fluidized bed but as its use is more associated with marine tanks and swimming pools I haven't had the opportunity to investigate or compare is to other media enough to form any sort of comparison which would enable me to make a video on it.
+Pondguru Outdoors thanks for the response. That's fair enough. I am planning to try it for the first time with some left over sand that I have, very fine sand. I'm sure it won't hurt anything but will be interesting to see its effectiveness. Keep up the good work!
I can't see any reason why that wouldn't work very well so I wish you the best of luck with it.
@@pondguru Wouldn't clog right up and become mud?
Biohome ultimate (or plus) vs biohome maxi size question..
Am I right in thinking that if smaller pieces of biohome have a larger surface area, they will support more aerobic bacteria, but larger pieces with a lower surface area to volume ratio will be able to support slightly more anaerobic bacteria, as more of the volume of the media will be in the middle, as opposed to at the edges. Worth including both in my filter at once, or is the smaller media better because I will ultimately be able to fit more in due to smaller size - fewer gaps?
They seem to perform the same and when there is no ammonia, nitrite or nitrate it is difficult to say which media is best, lol
If you have an external canister filter the ordinary size ultimate is the best as it fits in more efficiently but for a sump the larger size is betteras you can fill more space for the same cost.
pondguru I just set me up a moving bed filter for my 125 gallon aquarium. I used standard k3 media, the media seems to just be floating on top without much movement.. Is this normal when it is first set up? Does it take some time to start rotating around inside the bottle?
+Cody Medina K3 media is huge and better suited to large pond filters. You would be better off with K1 or ideally the new K1 micro. They will all take time to move and you should start with about a 25% fill until the bed moves well then add more as it moves freely.
How much k1 quantity required
I have a question I have a 10 gallon tank what size of a bottle do I use and how much media I put in it to get the proper filtration for that tank is there a chart that I can go by?
Fernando Miller Not really a chart since a moving bed filter is only one part of an aquarium filter, you also need mechanical filtration (as in 'how to' video link) and ideally a static part of filter which will remove nitrates. At a rough guess you would probably only need 250ml of K1 micro to handle waste in 10 US gal.
Thanks
can I use ceramic rings for my moving bed filter
They are too heavy to move. The media really needs to be either K1 or Hel-x for a DIY aquarium moving bed but the newer K1 micro is much better as it is very small which allows you to get much more into a fluid bed (with more surface area)
Hi, I've tried to make two of these diy moving bed filters but I'm having trouble getting the bottles to completely fill with water, I seem to get trapped air at the top and even though I've added extra holes to allow the air to escape it doesn't seem to? any ideas how to solve this please. my media moves round nicely within 48 hours but I'm not sure if water will be passing through the filter if it isn't full
Sounds like there may be too much air going into the bottle or the design of the bottle traps air? Feel free to send pictures to pondguru@btinternet.com and I'll see if there is anything which may be causing the air build up (plus give me details of the amount of air going into the filter(s) and that will help too).
Regards,
Richard
Can you in theory, in a sump, put a static bed of something like biohome ultimate before your moving bed? Would this not take care of your nitrates?
I had biohome in our sump for a while. Pulled it out because the sump is junk, but the media is great.
Are you experts in this field, in one of my aquariums, the k1 micro is slightly green it's probably algae? Will these beneficial bacteria multiply? ' In the second aquarium k1 micro is brown, probably good.
I don't consider myself an expert in anything but I do have areas of specialist knowledge. The dicolouration is good and will be a bacterial film building up. Really the darker it is the more mature it will be and eventually it will be brown / black depending on how much light it is getting. The green could be algae but more likely an organic film which will darken in time as it matures.
Just wondering if anyone uses Perlite as a filter media option? Any feed back will be good as I sell expended Perlite and crushed perlite ore.
I think it floats
Which air pump are recommended for moving bed media ( I have 20 gal pump but my k1 micro don't have moment) thanks
It depends on the size of the moving bed, placement of air outlet and shape of the container used for the filter.
20 g.p.h would be plenty for the moving bed at the start of this video but if there is too much media in to start with it will take an age to move. Try putting the air outlet at one side of the filter so the media moves in a cyclical motion and if it will still not move take some media out until the remaining media moves well then add more media every few days until the maximum stock of media is reached.
There is a risk with anything contained in a plastic bottle I suppose but in water a bottle would take many years to start the biodegrading process.
How do you crystalize-ink? basshead-Wetwillie
currently in the Philippines, where the bacterial balls are not available, unfortunately. they do, however, sell a liquid version of the beneficial bacteria, how effective is that, and would it be worth the investment?
The liquid additives are better than nothing and vary in quality. If you can get a powdered form of bacteria that may be a safer bet.
If the plastic media were to be given a rough surface would that make it easier for the bacteria to grow on?
Yes but producing small pieces of rough plastic which last a long time is very expensive. Plastic has no useful internal structure like ceramic or sintered glass media so will never come close to supporting as much bacteria but a moving bed does have the advantage of supporting very hardy bacteria which hammer the ammonia and nitrite (although they produce a load of nitrate).
cheers
hi Chis, Ciprian here with a question if I may, why can b used dynamic (balls) and static (sticks) filtration medium and, more than that what is the big difference between this 2 (how the motion or no motion due the work)?
all my gratitude for ur work u do here, learning us about this fantastic 'world'
+cip scu Not sure I understand the question entirely but the main difference between a moving and static bed is that a moving bed never needs maintaining as it is self cleaning. The moving bed can produce quite a lot of nitrate but is very effective at quickly processing ammonia and nitrite. A static bed is really only as good as the media used in it as it relies entirely on a good balance of aerobic and anaerobic bacteria to complete the nitrogen cycle (reduce ammonia, nitrite AND nitrate) and very few filter media types are good enough to support enough anaerobic bacteria to reduce nitrate. Biohome is the most effective.
cheers Chris, I were asking how this effect of moving is contribute to growing bacteria (there are a different species of bacteria working only in motion, dynamic environment comparing with static one?)
also, another question is about carbon medium used in filtration, this is working as a chemical filtration only?
+cip scu The moving beds tend to favor the aerobic strains of bacteria as it is a highly oxygenated environment with limited surface area for colonisation. That results in production of nitrates.
With regard to carbon yes it is almost entirely a chemical filtration product as although it has an incredibly porous structure the holes through it are so tiny they draw in pollutants from water then get rapidly clogged (hence the need to change it every 7-8 weeks).
Proper biological filter media should stay in the filter for many years.
cheers Chris, I am about to make my own filter like that one you made from white tube, I will let you know about it when done. good day!
What I am still confused about is how to decide how much "fluidized" and how much "static" is appropriate and what the tradeoffs are.
I have a bag of K2 here that I bought by accident a couple of years ago, can I use that or do I really have to buy K1? I could really use not to spend the money for more K.
Any moving media will do as long as the container you're using is a suitable size so no worries there.
What about K3 media?
What is the benefits of Moving Bed Filter??
Hello Pondguru, what is your opinion of lava rock that does not move vs K1 in a moving bed filter?
If it is the scoria (reddish brown lava rock then it is decent but lacks the structure to support much anaerobic bacteria so you get the same results - reduction in ammonia and nitrite with high nitrates.
So, using lava rock vs K1 would yield the same levels of ammonia reduction?
It would depend how much was used and in what situation but given that both types of media are really only capable of supporting aerobic bacteria the end result would be good reduction in ammonia and nitrite but high nitrate due to the media's lack of anaerobic bacteria to process the nitrate (meaning you'd keep the nitrate down by doing regular water changes).
Got it. Thank you
How long does it take for the K1 micro to completely colonized by bacteria ? I just recently installed a DIY moving bed filter in my tank so I'm just wondering how long it's going to take.
+paul nguyen Complete colonisation would include anaerobic bacteria and that can take many years (when the K1 gets really coloured up inside by a thick biofilm) but for the aerobic bacteria which controls ammonia and nitrite it usually takes 5-6 months in a pond environment and 4-5 months in an aquarium environment where water is warmer - even then the time can vary wildly.
I got some of your filter balls when I purchase the K1 micro and I put them in the moving bed filter to help speed up the process so I'm just wondering how long the filter will start to work
+paul nguyen It will start colonising straight away but for it to build up a sufficient colony to process ammonia and nitrite effectively please refer to previous answer.
I am also going to make this
Hey man just watching a few of your videos and one in particular you talk about how you need roughly 1kg of static media per 100litres of water at general stock levels, how would you compare moving media's to that? Will you be able to do a complete cycle?
With the biomotion I showed in this video it was possible to achieve a full cycle in a moving bed but the manufacture of it was so difficult, messy and time consuming that we had to drop that from our product line unfortunately. We were going to keep it up but the manufacture uses the same machinery as the biogravel so a 2 hour clean up of machinery every time we pt a batch of biomotion through was time wasted when it could have been turning media out.
Sorry, a bit more information than you probably needed there but the summary would be that there are no types of moving bed media available now which do anything other than the aerobic side of the cycle (for ammonia and nitrite removal) - they may do that very well but you will still need a static bed of suitably porous media after that to allow for the last stage of cycle, anaerobic for nitrate removal.
@@pondguru never too much info, thanks for that. Would it be more efficient to use another media in a moving bed and then have static media to complete the cycle or just use static and have a good mechanical filter before hand so you don't have to maintain the bio filter as much?
Once a moving bed is mature (which can take up to 6 months with plastic media) it will do a great job of removing ammonia and nitrite very quickly but really you'd only employ a moving bed plus a static bed in a sump where there is plenty of available space. In a 'normal' set up you can easily achieve a full cycle simply by using an appropriate amount of good media and a well-sized, properly set up filter. As long as you have good mechanical filtration before good porous media there is no 'need' for a moving bed but in sumps some people will have a highly oxygenated moving bed followed by a slow flow area of porous media so they can imagine that each section does a certain stage of the cycle.
OK awesome thanks a bunch, definetly earned my subscription though I wish I had seen this before production ended.
How much K1 Micro (in gm) needed for a 1.5lt and 2lt bottle?
It would be around 1 litre for the 1.5 litre bottle and 1.5 litres for the 2 litre bottle but it depends on the shape of the bottle.
Nice video Pond Guru. Uber practical as usual. I've got Koi Carp and treasure hunting in my latest video especially for you. Metal detecting Japan. Silver, coins and artifacts.
Awesome location and Japan could well hold great finds as it will have hardly been touched - best of luck out there, man.
Im in Australia and have had trouble getting BIO MOTION is there any online stores that ship to aus??
I ship worldwide (link in video description) but shipping can be a killer to AU.
Have you tried the AU supplier of biohome? They should have all types in stock and the link to their site is on every page of my website (AU flag at top right of page).
Hope that helps.
+Pondguru Outdoors i just checked the aus suplier and emailed them but doesnt say they have any on the onilne store
They may not have any as the mini ultra, ultimate / marine and ultra outsell the biomotion by a huge amount. However he may have a limited amount available so hopefully a reply to your email will be positive.
Can you use biomotion with k1
Yes it could be used with any plastic media but we don't make the biomotion any more as people reported it was noisy when used indoors. Also it was a very messy and time consuming process to make it which used the same machinery as the new biogravel and shower media so it was taking as long to clean the machinery as it was to make the mix up.
Any chance of Hel-X micro?
Probably not but that would be the next logical step and would be awesome.
