as to your flat bottom barrel, try this, using a barrel that is shot in the side for practice, set the flat on some blocks about 3 ft high, place a 5 gal bucket of sand in the barrel, then from the underside, use a heat gun or some other heat source to make the plastic pliable, the weighted bucket will apply an even pressure and should help the bottom to sag forming a more conical bottom.
I'm a beginner in this Aquaponics here in Thailand. I've viewed dozens of UA-cam video's trying to get a grasp of how to do things correctly. Many video's have been okay, however your channel and information you provide is excellent and really appreciated, thank you.
great article in the links below, thank you, by the way to make a conical bottom on a blue bin like that, try using any round weight, with a few bricks on it, in center of bin , with bin off the ground and only supported at edges, then simply heat using a heat gun (in an area with plenty of ventilation) soften it up and it slowly stretches out, do not do it too much or the base will get too thin , heat evenly and take your time is the key here, few goes and you get it pretty good each time, will not be a $500 tank but enough to get solids to settle closer to outflow to have most sucked up each time

Dumb question? I have watched so many of your videos (they're great! Thanks so much!) , but I can't figure out the start point - HOW are the waste solids and water being pulled up that pipe (solids lifting outlet)? 1:30

@@RobsAquaponics thanks so much, Rob!! That was a good explanation for me! (A little embarrassed about not just "getting it", lol! I was going to find and delete my question and then it features in your next video!! 😂)
@@infiniLor Don't be at all mate. Took me a while to get my head around it when I first started. 👍 I was told by a few folks that I was better off running the system with 2 pumps, one in with the fish & one in the sump. I'm glad I never listened😉👍
@@RobsAquaponics thanks!! There certainly a lot of moving parts to these systems, but your collection of videos are incredibly helpful - really feel like I'm getting more and more of it all. THANK YOU FOR ALL YOUR WORK
Thanks Rob, great video, always so helpfull! a suggestion for the outlet of the pipe that comes close to a professional RadialFlowSettler: you could cut the slit on the outlet pipes, which you make double (in a fork shape), zig zag instead of one elongated slit on each side. water is wetting. when water runs over a horizontal barrier, it usually creates a wider jet of water in the middle, rather than a flat jet of water that spreads across the entire width of the barrier. I would therefore zigzag the slit so that the overflowing water splits into many small jets of water. That might slow down the water flow a bit more.
Thanks for that Paul. I have contemplated that but never got around to installing the extra pipes. It was putting too much weight on the drain pipe leaving the filter. Might have another crack at it though as the exit drain arrangement has changed now the biofilter has been installed. Cheers.
Rob, instead of one large drum for the solid filter, would it be possible to chain several radio flow systems consecutively with the cheaper buckets 200 L buckets? That way you increase the overall retention time while keeping costs down? Of course this would still require more space though.
That's essentially what I'm doing. I've got 2 x 200L tanks in series; effectively that gives me about a 10 min time for water to move from the fish tank before it hits my MBBR. You'll notice a significant difference in the deposition load between the two tanks. About 7/10 of the material is in the first tank, and the remainder is in the second tank. I've got a set of filter brushes in the second tank for mechanical filtration of the micro-fines before they get into the MBBR.
I think it would be better to run them in parallel than series K JC. That way you're dropping the flow rate into both settlers which would be doubling your retention time.👍 Cheers.
Brother I cannot thank you for all that you do to guide us! You’re a wonderful human! Could you give me any pointers on a system where a fish tank (100 gallon) would be located in my home but the rest of my system about 40 feet away? Thanks!
Hi SelfBuilt & sorry for taking a while to get back to you. Sounds like you would need some decent plumbing underground to achieve this. if the grow beds were out in the yard. Would work better if the beds were located next to the house so you could run the overflow from the FT directly into the beds at level, say if the beds were along the wall of the house. Once you send pipe underground you will have solids build up in there that will need cleaning from time to time.
I have a silly question, but how does the water flow from the fish tank to the radial flow settler? I don't see a pump or anything and it doesn't seem like gravity could go from the bottom of the fish tank up and then again from the middle of the radial flow filter to the top. Thank you for all your cool videos!
Hey Lemon Song. The water coming into the fish tank causes water & solids at the base of the tank up the Solids Lifting Outlet (SLO) pipe & out the side wall of the tank. 👍 This link will take you straight to a section in another video that will give you a visual explanation. ua-cam.com/video/0QQA5BpWKec/v-deo.html Hope that helps some.
It wouldn't create enough flow for the amount of water exchange I like in my fish tank. Land to House has a great explanation if it helps any. ua-cam.com/video/T2idony585A/v-deo.html Hope that helps.
Hi Rob, if your still look for bracing ideas, you could run the two lengths of pipe through the back of the tank with the same seals you use elsewhere and then cap it.
I deal with settling velocity a lot with my gold mining, it's interesting seeing the same principles applied to other applications. Another filter method is called a lamella clarifier or inclined plate settler.
I've seen a some similar in design used in aquaponics systems but more the larger commercial systems 👍 Do you earn an income from mining or is it just a hobby if you done't mind me asking.
@@RobsAquaponics I've been a professional gold miner since 2006. I have an ownership stake in 19,000 acres of mining rights in Alaska. I am finishing a capital raise to complete the largest gold mining operation of its type in North America.
@@TagiukGold Nice one mate. 👍👍 Hope you can get the funding you need mate. Not sure how you could live up there though. I'm sitting here in 3 layers at the moment as it got down to below 0°C/32°F here last night.🤣 The subtropics has made me soft I think. 😉 Cheers.
I have seen folks do that & it works well. Can be a bit messy to clean & you'll probably need to dump most of the water come cleaning time. Might have a few issues if you don't clean the netting out frequently. Cheers Ivan.
Does the solids lifting outlet have to be at the waterline like you have in the video or could you have it below the waterline? I feel like you would have better flow if the pipe was underwater and your siphon prevention pipe was still out of the water
There is generally no issues with flow rate as long as you have the pipe sized correctly for the flow rate. If the outlet was lower the water would naturally drain to that level 👍
I have seen folks use those to clean out the base. 👍 I was using a jiggle siphon to start out with. but found using the waste valve a lot faster. Cheers & have a great one.
Enjoyed the video trying to learn how to do aquaponics. Way before I start actually doing it 😂 very interested in doing it though. Thanks for information about it. I'll keep on watching. Have a great day
Your explanations are very clear.Thanks for posting.We plan to use swirl filter in our unit. Could you share mineralization and oxygenation of fish waste? Would that make it easier on maintenence should the above step is used? Happy aquaponics
Hi Rob I'm just in the process of building a radial flow settler. I have a piece of 150mm pipe like you used, or I have z piece of 200mm pipe. Would the larger diameter pipe increase or decrease retention time. Thanks in advance.
Hi MFL. The total volume of the drum will dictate the overall retention time. 👍 I do think that the 200mm pipe would allow the water to slow down a bit more before entering into the main chamber though which could help some. Hope the build is coming along well.
Thanks for your excellent videos. What is the problem with just depositing the fish waste directly into your grow beds? I assume they'll end up fouling your system. I am certain the plants would like the fish poop. Thanks for any answer.
Would be a great idea as long as the plants got enough sun. 👍 Will be building a structure in the backyard for the larger system I'm looking at setting up. Cheers.
Love you videos. Just bought a house with 2 acres in Canada Hoping to start setting this up for next growing season. Any tips for cold northern climates? How are the solids picked up? I didn't see a pump or anything connected to that plumbing.
Hey Marty. Setting the fish & filters up inside (basement or warm garage) or well sealed greenhouse will help keep them warm through winter. You can then run the water outside to the hydroponic side, or do that inside as well depending on space. This video will help explain how the solids move from the fish tank to the filters, ua-cam.com/video/2FTlha0c2aA/v-deo.html Cheers & have fun with the build when the time comes.
I am new to this and mostly helping a neighbor setup his. You mentioned the settler tank should be bigger. My question is if I'm using ibc containers can I use a second for my settler tank? Would that give me the 15 minutes needed?
Glad I could help mate. Still haven't set up the new garden beds so I can move the mulch from our driveway mate. 🤣 Maybe next week looking at how busy this weeks going to be. Cheers Steven & have a top one mate.
so i'm making a 10 gallon Aquaponics system and am confused because I've never done this before and am confused on the basics and don't fully understand the steps to making a system got any advice on how to get the bacteria in the system and how big a pump ill need for the grow bed circulation if i were to put the bed over top the tank
hello, i just found out your channel and its really a God send, im in the process of watching all of your videos in order to put order and have a little bit more of influence on how I would design my own system. In this video, i still don't understand the meaning of the retention time, why would one want a longer vs shorter time? thank you!
Retention time is the time the water spends in the container. The longer the water stays in their, the longer the solids have to fall out of the water column so they can be collected from the vase of the settler. Hope that helps some. 👍
Maybe you can cut a piece of plastic to fit in like a cone at the bottom of the tank. With the discharge Port the middle of the bottom of the cone. If you want 45° sides, then multiply the radius of your tank by 1.414 . cut a circle of flexible plastic with Vishnu radius, then cut a pie slice out of it and a small circle in the middle where your outflow will fit. Then you can notch the edges where the pie slice came out and the outflow pipe goes through. If you want it to clean automatically, then put the pump on a timer and make a loop to above the height of the radial flow filter and install an air gap. This way the pump does not have to seal and you can put it on one of those timers that you plug into the well. Yes they had a bit of complexity, but you wouldn't have to manually flush your filter and your water quality would be more consistent. Keep up the good work Rob Bob. I truly value people like you who share their skills and try to encourage others to be involved in worthwhile hobbies
I like the idea of having the pump on a timer Glen.👍👍 Have seen folks add a cone into the base of their 55gal drums & they do work. Would have a propper crack if I had a plastic welder. Many will also pack the internal walls of the filter with cement to form a cone then seal it with a food-safe sealant. They can then plumb the outlet into the centre of the flat base of the drum which makes life easier. I'm fairly happy with the set up as it stands but would like to get propper cone base tanks for the settler & bio in the next large system we'll be setting up here. Cheers mate & have a top one.
Great vid as always, I’m learning a lot. Think I’ll go with simple Dutch bucket hydroponic system this year and maybe upgrade to aquaponic system next year.
Hey Rob, have you tried having 2 radial flow filters connected parallel to each other? This way you can double the volume and retention time and still use the cheap components.
Also I had another though. Do you need that much water flow through your fish tank? You mentioned many times that you need to pump the entire volume of the growbed twice an hour for the bacteria to work. But that has to go through the growbed, not through the fishtank, right? So if you have a split system you could slightly close the valve on fish tank side and reduce flow through the fish tank by half. In theory that would double the percentage of ammonia in the fishtank water but since we are removing half, it would equalize and the same amount of ammonia will escape the tank. The only question is if doubling ammonia concentration in the fishtank water wont kill the fish.
I haven't due to space issues but think it could be done mate & the decrease in flow would help to a point. 👍 I'm not sure it would really be worth it in a small system like this current one I have on the go. Cheers mate.
@@hubertnnn The fish tank water needs to go through the beds twice an hour as that's where the ammonia is coming from & we want it processed ASAP so as to not build up & harm the fish. 👍 Hope that helps.
Great video, as always Rob! Have you thought about putting in a bio filter after your RFS? I use a 200l RFS into a 200l bio filter before going into my media bed
There is one of sorts in the sump that's filled with shade cloth but nothing like the old setup I had. I'm going to remove it though & turn it into a static pack trickle bio/solids filter though as the shade cloth is a real pain in the rear to clean. Cheers Indica Dogo & have a top one.
You can just use gravity. I like to use a small pump as it creates a greater drag on the solids + I'm also now pumping the solids up into a tall mineraliser drum at the moment.
I have the water in a storage drum to let the chlorine off gas. You can see it in one of my more recent clips. ua-cam.com/video/H-jfWMpZXHI/v-deo.html If you have rain water tanks you can add water directly from them if you think they're not contaminated in any way. Hope that helps.
Some folks have something similar on theirs Michael. I just haven't found the need myself in these smaller systems. Thanks for jumping onboard the members page as well mate. 👍 Cheers & happy growing 🌱🐟
This stand was custom build for the bed by the chap I bought it from SC. I'm yet to find a place that sells the troughs with a suitably high stand. Cheers.
Thanks for your video. If I wanted to have a longer retention time and can't find a larger tank, can I achieve the same results (increase RT) by putting 2 tanks in series?
Parallel would be better Amanda as you would be splitting the flow rate into 2, effectively halving it. That should double your overall retention time. If they were in series the water would still be flowing at the same rate but I dare say some extra would be collected in the second filter, not as much as if the filers were in parallel though. Hope that helps some.
Hey Rob it is possible to have the cone inside the settler too you may loose a little volume inside but it is possible to have 4 smaller pieces of plastic that would be angled in a fashion that will force the solids to congregate at a single point..
There's no reason you can't Lincoln. Have seen many settlers with cone bases. Only reason I use the flat based drums is due to price & that the drain system I sues cleans them out just as well. Cheers.
Hey Rob thanks for a great video! In your opinion what will be the most low maintenance filter or settler for IBC tote fish tank and grow media systems?
Thanks & sorry it took a while to get back to you Cosirius. I would think that the radial flow settlers would have to be the best DIY solids solution. For a commercial unit (hobby or commercial system size) , I like the AST bead filters. astfilters.com/aquatic-systems/project/bubble-bead-filter-for-aquaponics/ They also add extra biological filtration so would be a great addition (if you have the coin) to a NFT or DWC based grow system I think. Hope that helps some.
I was looking to build a gravity fed swirl filter for a 300 gallon stock tank duck pond. I'm now thinking that one of these would be better at keeping the "solids" solid, vs emulsified at faster swirl/vortex speeds? That's the theory at least.
Nice idea WOB. 👍 Would be a lot easier to set up than a cone base. 😉 Would still like to weld it in place so no water or muck gets under it causing issues down the line. Cheers.
Thanks for sharing. New to your channel I’m going to convert my in ground pool to this system . Watching and learning. I want to use CatFish in my pool it’s 20’x30 feet 8 feet deep. I’m in Louisiana USA
Sounds like quite a system. 👍 Just remember that you need a large enough bio filtration system to convert the ammonia that the fish produce. I've seen folks add a load of fish in pools & they end up dying as they produce far too much ammonia for a small amount of grow beds to handle. The other issue can be that adding too few fish means the ammonia is very dilute & the plants don't grow very well. Not a real issue if you're in it just for the fish. Hope that helps some mate.
Rob why not pump to your radial settler and that way you can set your detention time for whatever you want and you don’t have to worry about the height of the radio flow filter?
Hey Aaron. I prefer to keep the pump out of the fish tank & in a separate sump in my builds. Have seen systems where a pipe comes lose & all the water is pumped from the tank leaving some very dead fish. Cheers mate.
@@RobsAquaponics Thanks rob for your response. I am thinking about putting a sump between the fish tank and the radial filter thus avoiding the failure mode you described. I was just curious if the radial filter becomes less efficient because all the solids are going through the pump and becoming finer? I suppose I could adjust the detention time given I would now be pumping to the radial filter... It's probably tough to measure, but your opinion is valuable. Anyway, thanks for your work. You've inspired our family to aquaponics... Greenhouse coming soon! Take care.
@@MrAaronCard Thew pump will smash the solids into finer particles so would need a longer retention time to fall out of suspension. The settler will do a better job before the sump but the fish will be safe in either position as long as the water leaves the FT via a solids lifting overflow/outlet.
This might help Anthony, ua-cam.com/video/NUX0BOi-too/v-deo.html It's a brief explanation of how the lifting outlet works & delivers the water out to the settler. Sorry it took a while to respond.
Parallel would be better as it would increase the overall retention time. I posted a bit of information on it in this video. ua-cam.com/video/VgBuUFx_xOE/v-deo.html Hope that helps some.
I believe this on a larger scale would work for dropping out solids form a creek water source for irrigation. We have a gravity feed water system getting water from a reliable creek source but in the spring with runoff, the water gets a ton of solids in it as it comes for kilometres before we access it. Do you think this is possible?
I'm trying to add one of these filters to a chop and flip system, no sump tank. Would I put the pump in the 55 gal drum so that it would pull the water from the fish tank?
Probably not a good idea as it will disturb the solids some what. A small DIY canister filter would be what I recommend Jim. ua-cam.com/video/HtMZRM3a5Fs/v-deo.html Hope that helps some.
My guess is that you would see more benefit from putting the filters in parallel. Retention time is basically a measure of upwelling speed, which you want as slow as possible in order to allow the finer particles, which have lower settling velocity, time to fall out.
Have you considered putting sump tank underground for temperture control? This way u dont have to lift growbed up and they can stay safe and steady on the ground
Unfortunately that's a but hard in this location due to the sewer drain pipes under ground here. I did have the last sump partially buried but not too deep due to some very large tree roots from out mango tree. Definitely worth doing if you can though. I'd still keep the beds up this high though for ease of use. Would help to have some lower beds for tall growing veg like tomatoes though. Cheers Yan He. 👍

Reading the paper and comparing results of Swirl and Radial Flow, cannot see a statistical difference.

Thanks for including the paper and I'm glad you trying new stuff!
Rob which cut off or ball valves have you found the best ( easiest ) to open and close. I keep tropical fish as well and use vast amounts of valves in the fish room, some require Popeyes arm and cans of spinach to open. Thanks Ps I live in southern Ga in the states
I like the Sanking 3002 - Series Ball Valve & think that they're available in the US. Have found them fairly easy to operate when compared to others I've tried. I was drawn to them mainly as the handles are removable. I switched to them after we had visitors kids turn a few valves on & off while I was chatting aquaponics with their parents. 😉 Sorry I'm not much help there mate.
Hi Rob, I'm yet too setup a small aquaponics system here and confused by to many reference. Should the water pass through biofilter bed (grow bed) and then to the deep water culture or can i bypass the grow bed and flow water to DWC?
You can bypass the grow bed if you think you have adequate solids filtration Mandan. It's best to remove as much solids as you can before adding the water to the DWC.
Is it possible to set up simple/reliable hydro/aqua system that will hum along without daily intervention when I take off and hit the road for a few months of vacation travel?
Quite possible but plant selection would be key. A lot of leafy greens are fast growers so may be finished before you get back. You'd also need to automate the nutrient dosing & water control as well.
Hi Rob thanks for the clip ! Rob can a person plumb 3 ibc's into one settler? And also I have found abs fittings and pipe are alot more affordable /avaliable thanks Rob
You can but it will reduce the retention time which in turn will mean a lot less solids will be captured for removal later George. If the settler was 500+L/130+gal it may do an OK job.
Hey. My 55 gallon drums form heavy sulfides. I have 14,000 L pools. I dont want to pull too much so i have a smaller settler. Im a shrimp farmer in the states and use biofloc from ammonia management. Love your set up. I cant make em work without sulfides. If you could address that issue id be very grateful.

Hey Rob! love your videos they are really insightful! Wondering if it possible for you to upload a list of materials that you have used in this particular build and their individual sizes (pipes etc). i know what a pain, but would really appreciate!
Will look at adding something to the website Jamie. Shall notify folks in a clip or Facepalm once it's uploaded. Probably best to not hold your breath though as it might take a week or 2. 😕
Great stuff as always Rob! One idea, could you not do a T-split from the SLO and into 2 X 200L settlers for a cheap 12min retention time? :) (as an alternative to a really expensive 500L version). Also love the idea of the “fork” water outtake for the settler to slow it down. Might need to play around with that idea myself :D
A few folks have suggested that & it would increase the RT dramatically.👍 Helps if you have the space to be able to set it up & would work out a lot cheaper than a larger single tank. Hope the build goes well. 👍

as to your flat bottom barrel, try this, using a barrel that is shot in the side for practice, set the flat on some blocks about 3 ft high, place a 5 gal bucket of sand in the barrel, then from the underside, use a heat gun or some other heat source to make the plastic pliable, the weighted bucket will apply an even pressure and should help the bottom to sag forming a more conical bottom.

great article in the links below, thank you, by the way to make a conical bottom on a blue bin like that, try using any round weight, with a few bricks on it, in center of bin , with bin off the ground and only supported at edges, then simply heat using a heat gun (in an area with plenty of ventilation) soften it up and it slowly stretches out, do not do it too much or the base will get too thin , heat evenly and take your time is the key here, few goes and you get it pretty good each time, will not be a $500 tank but enough to get solids to settle closer to outflow to have most sucked up each time

Thanks Rob, great video, always so helpfull!
a suggestion for the outlet of the pipe that comes close to a professional RadialFlowSettler: you could cut the slit on the outlet pipes, which you make double (in a fork shape), zig zag instead of one elongated slit on each side.
water is wetting. when water runs over a horizontal barrier, it usually creates a wider jet of water in the middle, rather than a flat jet of water that spreads across the entire width of the barrier. I would therefore zigzag the slit so that the overflowing water splits into many small jets of water. That might slow down the water flow a bit more.
Thanks for that Paul. I have contemplated that but never got around to installing the extra pipes. It was putting too much weight on the drain pipe leaving the filter. Might have another crack at it though as the exit drain arrangement has changed now the biofilter has been installed.
Cheers.
Wonderful very informative
Just fond your channel, got to say its awesome, got some really interesting stuff going on
Welcome aboard & thanks Dan.👍
Cheers & happy growing.
Rob, instead of one large drum for the solid filter, would it be possible to chain several radio flow systems consecutively with the cheaper buckets 200 L buckets? That way you increase the overall retention time while keeping costs down? Of course this would still require more space though.
K JC my thought too but parallel to slow the water even more.
That's essentially what I'm doing. I've got 2 x 200L tanks in series; effectively that gives me about a 10 min time for water to move from the fish tank before it hits my MBBR. You'll notice a significant difference in the deposition load between the two tanks. About 7/10 of the material is in the first tank, and the remainder is in the second tank. I've got a set of filter brushes in the second tank for mechanical filtration of the micro-fines before they get into the MBBR.
will have to be in parallel not in series or you could use another IBC
I think it would be better to run them in parallel than series K JC.
That way you're dropping the flow rate into both settlers which would be doubling your retention time.👍
Cheers.
Brother I cannot thank you for all that you do to guide us! You’re a wonderful human! Could you give me any pointers on a system where a fish tank (100 gallon) would be located in my home but the rest of my system about 40 feet away? Thanks!
Hi SelfBuilt & sorry for taking a while to get back to you. Sounds like you would need some decent plumbing underground to achieve this. if the grow beds were out in the yard. Would work better if the beds were located next to the house so you could run the overflow from the FT directly into the beds at level, say if the beds were along the wall of the house. Once you send pipe underground you will have solids build up in there that will need cleaning from time to time.
I have a silly question, but how does the water flow from the fish tank to the radial flow settler? I don't see a pump or anything and it doesn't seem like gravity could go from the bottom of the fish tank up and then again from the middle of the radial flow filter to the top. Thank you for all your cool videos!
Hey Lemon Song.
The water coming into the fish tank causes water & solids at the base of the tank up the Solids Lifting Outlet (SLO) pipe & out the side wall of the tank. 👍

1:52 what is the reason of using 2pcs of 45 degree elbow instead of 1 90 degree elbow????
Slower turn to obstruct the water flow less.

I deal with settling velocity a lot with my gold mining, it's interesting seeing the same principles applied to other applications. Another filter method is called a lamella clarifier or inclined plate settler.
I've seen a some similar in design used in aquaponics systems but more the larger commercial systems 👍
Do you earn an income from mining or is it just a hobby if you done't mind me asking.
@@RobsAquaponics I've been a professional gold miner since 2006. I have an ownership stake in 19,000 acres of mining rights in Alaska. I am finishing a capital raise to complete the largest gold mining operation of its type in North America.
@@TagiukGold Nice one mate. 👍👍 Hope you can get the funding you need mate.

Cheers.
Would you slow down the water flow if you added bristles that hang into the water? An old broom head glued to the lid for example.
That would work + it would help to collect some of the fine solids as well. Might add that to the "to try" list.
Thanks Hannes. 👍
Thanks a lot for this ....needed it thanks a ton
Glad it helped some.
Cheers.
hi. just a question. can i put in fishnets or shade cloths inside the filter to further help in filtering the water going out? or is it not necessary?
I have seen folks do that & it works well. Can be a bit messy to clean & you'll probably need to dump most of the water come cleaning time. Might have a few issues if you don't clean the netting out frequently.
Cheers Ivan.
Does the solids lifting outlet have to be at the waterline like you have in the video or could you have it below the waterline? I feel like you would have better flow if the pipe was underwater and your siphon prevention pipe was still out of the water
There is generally no issues with flow rate as long as you have the pipe sized correctly for the flow rate.
If the outlet was lower the water would naturally drain to that level 👍
Could you use a gravel cleaning type tube to suck all the crud out as well?
I have seen folks use those to clean out the base. 👍 I was using a jiggle siphon to start out with. but found using the waste valve a lot faster.
Cheers & have a great one.

Hi Rob
I'm just in the process of building a radial flow settler. I have a piece of 150mm pipe like you used, or I have z piece of 200mm pipe. Would the larger diameter pipe increase or decrease retention time.
Thanks in advance.
Hi MFL.
The total volume of the drum will dictate the overall retention time. 👍 I do think that the 200mm pipe would allow the water to slow down a bit more before entering into the main chamber though which could help some.
Hope the build is coming along well.
Thanks for your excellent videos. What is the problem with just depositing the fish waste directly into your grow beds? I assume they'll end up fouling your system. I am certain the plants would like the fish poop. Thanks for any answer.

Love you videos. Just bought a house with 2 acres in Canada Hoping to start setting this up for next growing season. Any tips for cold northern climates? How are the solids picked up? I didn't see a pump or anything connected to that plumbing.
Hey Marty. Setting the fish & filters up inside (basement or warm garage) or well sealed greenhouse will help keep them warm through winter. You can then run the water outside to the hydroponic side, or do that inside as well depending on space.
This video will help explain how the solids move from the fish tank to the filters,

I am new to this and mostly helping a neighbor setup his. You mentioned the settler tank should be bigger. My question is if I'm using ibc containers can I use a second for my settler tank? Would that give me the 15 minutes needed?
You can if you have the room Michael. Might be a bit tricky trying to collect the solids from the base regularly though.
Have fun with the build mate.

hello, i just found out your channel and its really a God send, im in the process of watching all of your videos in order to put order and have a little bit more of influence on how I would design my own system. In this video, i still don't understand the meaning of the retention time, why would one want a longer vs shorter time? thank you!
Retention time is the time the water spends in the container. The longer the water stays in their, the longer the solids have to fall out of the water column so they can be collected from the vase of the settler.
Hope that helps some. 👍
Maybe you can cut a piece of plastic to fit in like a cone at the bottom of the tank. With the discharge Port the middle of the bottom of the cone. If you want 45° sides, then multiply the radius of your tank by 1.414 . cut a circle of flexible plastic with Vishnu radius, then cut a pie slice out of it and a small circle in the middle where your outflow will fit. Then you can notch the edges where the pie slice came out and the outflow pipe goes through. If you want it to clean automatically, then put the pump on a timer and make a loop to above the height of the radial flow filter and install an air gap. This way the pump does not have to seal and you can put it on one of those timers that you plug into the well. Yes they had a bit of complexity, but you wouldn't have to manually flush your filter and your water quality would be more consistent. Keep up the good work Rob Bob. I truly value people like you who share their skills and try to encourage others to be involved in worthwhile hobbies
I like the idea of having the pump on a timer Glen.👍👍
Have seen folks add a cone into the base of their 55gal drums & they do work. Would have a propper crack if I had a plastic welder.
Many will also pack the internal walls of the filter with cement to form a cone then seal it with a food-safe sealant. They can then plumb the outlet into the centre of the flat base of the drum which makes life easier.
I'm fairly happy with the set up as it stands but would like to get propper cone base tanks for the settler & bio in the next large system we'll be setting up here.
Cheers mate & have a top one.

If you need more Retention time use a IBC as your radial flow filter...

@@RobsAquaponics Hello teacher, do you have chemical solution to make Nitrosominas and nitrobacter bacterias? My filter hasn't has enough bacteria .
@@savatnut192 I just supply a ammonia source then they will colonise by themselves as they are in the air & on surfaces all around us.
Cheers.
@@RobsAquaponics I use NH4Cl for running my system.
Hey Rob, have you tried having 2 radial flow filters connected parallel to each other?
This way you can double the volume and retention time and still use the cheap components.
Also I had another though.
Do you need that much water flow through your fish tank?
You mentioned many times that you need to pump the entire volume of the growbed twice an hour for the bacteria to work. But that has to go through the growbed, not through the fishtank, right?
So if you have a split system you could slightly close the valve on fish tank side and reduce flow through the fish tank by half.
In theory that would double the percentage of ammonia in the fishtank water but since we are removing half, it would equalize and the same amount of ammonia will escape the tank.
The only question is if doubling ammonia concentration in the fishtank water wont kill the fish.
I run 2 radial flow filters (55g drums) in parallel. Works great.
I haven't due to space issues but think it could be done mate & the decrease in flow would help to a point. 👍 I'm not sure it would really be worth it in a small system like this current one I have on the go.
Cheers mate.
@@underdog5004 Cheers mate. 👍👍
@@hubertnnn The fish tank water needs to go through the beds twice an hour as that's where the ammonia is coming from & we want it processed ASAP so as to not build up & harm the fish. 👍

Great video, as always Rob!
Have you thought about putting in a bio filter after your RFS?
I use a 200l RFS into a 200l bio filter before going into my media bed
There is one of sorts in the sump that's filled with shade cloth but nothing like the old setup I had.
I'm going to remove it though & turn it into a static pack trickle bio/solids filter though as the shade cloth is a real pain in the rear to clean.
Cheers Indica Dogo & have a top one.
hi do u really need a pump to remove the solits or can u just use gravity?
You can just use gravity. I like to use a small pump as it creates a greater drag on the solids + I'm also now pumping the solids up into a tall mineraliser drum at the moment.
Whenever you are pumping out the solids, from where you taking the make up water? Can it be taken from the taps directly?
I have the water in a storage drum to let the chlorine off gas. You can see it in one of my more recent clips. ua-cam.com/video/H-jfWMpZXHI/v-deo.html
If you have rain water tanks you can add water directly from them if you think they're not contaminated in any way.
Hope that helps.
Watching through this video I had a thought, maybe a elbow up on the drain side would increase the waste captured?
Some folks have something similar on theirs Michael. I just haven't found the need myself in these smaller systems.
Thanks for jumping onboard the members page as well mate. 👍

Hi. Can you tell me where to find one of those metal stands that you are using for your grow bed in this video? Thanks!
This stand was custom build for the bed by the chap I bought it from SC. I'm yet to find a place that sells the troughs with a suitably high stand.
Cheers.
Can the end product 💩 be added directly into the garden or fruit trees or compost?
I just shared your video to my FB group. I hope that will increase your exposure, Mate, from a different place. :D
Thank you very much mate. 😁 Hope they get the idea.
Cheers & all the best.
Thanks for your video. If I wanted to have a longer retention time and can't find a larger tank, can I achieve the same results (increase RT) by putting 2 tanks in series?
Parallel would be better Amanda as you would be splitting the flow rate into 2, effectively halving it. That should double your overall retention time.
If they were in series the water would still be flowing at the same rate but I dare say some extra would be collected in the second filter, not as much as if the filers were in parallel though.
Hope that helps some.
Can biological filtration be added directly into this system?
IE. bio-beads?
Or do you put a separate bio bead filter after the mechanical filtration?
I prefer to have the biofilter separate to the solids filter. Makes life a lot easier when it comes to cleaning out the solids.
Hey Rob it is possible to have the cone inside the settler too you may loose a little volume inside but it is possible to have 4 smaller pieces of plastic that would be angled in a fashion that will force the solids to congregate at a single point..
There's no reason you can't Lincoln. Have seen many settlers with cone bases.
Only reason I use the flat based drums is due to price & that the drain system I sues cleans them out just as well.
Cheers.
A real gentleman.... Just saying!!
Cheers mate. 👍
Hey Rob thanks for a great video! In your opinion what will be the most low maintenance filter or settler for IBC tote fish tank and grow media systems?
Thanks & sorry it took a while to get back to you Cosirius.
I would think that the radial flow settlers would have to be the best DIY solids solution.
For a commercial unit (hobby or commercial system size) , I like the AST bead filters.
astfilters.com/aquatic-systems/project/bubble-bead-filter-for-aquaponics/
They also add extra biological filtration so would be a great addition (if you have the coin) to a NFT or DWC based grow system I think.
Hope that helps some.
I was looking to build a gravity fed swirl filter for a 300 gallon stock tank duck pond. I'm now thinking that one of these would be better at keeping the "solids" solid, vs emulsified at faster swirl/vortex speeds? That's the theory at least.
Would like to know how you get on if you give it a crack N4G. 👍
Good job sir. Iam arif. I also using RAS system for my tilapia farm.
Rob, place an elliptical plastic disk in the settler which will guide the gunk to the outlet tap.
Nice idea WOB. 👍 Would be a lot easier to set up than a cone base. 😉 Would still like to weld it in place so no water or muck gets under it causing issues down the line.
Cheers.
Thanks for sharing. New to your channel I’m going to convert my in ground pool to this system . Watching and learning. I want to use CatFish in my pool it’s 20’x30 feet 8 feet deep. I’m in Louisiana USA
Sounds like quite a system. 👍 Just remember that you need a large enough bio filtration system to convert the ammonia that the fish produce.
I've seen folks add a load of fish in pools & they end up dying as they produce far too much ammonia for a small amount of grow beds to handle.
The other issue can be that adding too few fish means the ammonia is very dilute & the plants don't grow very well. Not a real issue if you're in it just for the fish.
Hope that helps some mate.
Rob why not pump to your radial settler and that way you can set your detention time for whatever you want and you don’t have to worry about the height of the radio flow filter?
Hey Aaron. I prefer to keep the pump out of the fish tank & in a separate sump in my builds. Have seen systems where a pipe comes lose & all the water is pumped from the tank leaving some very dead fish.
Cheers mate.
@@RobsAquaponics Thanks rob for your response. I am thinking about putting a sump between the fish tank and the radial filter thus avoiding the failure mode you described. I was just curious if the radial filter becomes less efficient because all the solids are going through the pump and becoming finer? I suppose I could adjust the detention time given I would now be pumping to the radial filter... It's probably tough to measure, but your opinion is valuable. Anyway, thanks for your work. You've inspired our family to aquaponics... Greenhouse coming soon! Take care.
@@MrAaronCard Thew pump will smash the solids into finer particles so would need a longer retention time to fall out of suspension.
The settler will do a better job before the sump but the fish will be safe in either position as long as the water leaves the FT via a solids lifting overflow/outlet.
Hey Rob, How does the water flow from the tank, what makes it go through the bottom pipe and not over the sides of the fish tank instead?

GRATITUDE 💥🐟💥
I believe this on a larger scale would work for dropping out solids form a creek water source for irrigation. We have a gravity feed water system getting water from a reliable creek source but in the spring with runoff, the water gets a ton of solids in it as it comes for kilometres before we access it. Do you think this is possible?
It would depend on your flow rate I would think. For finer solids I'd be looking at 15 min + of retention time.
I'm trying to add one of these filters to a chop and flip system, no sump tank. Would I put the pump in the 55 gal drum so that it would pull the water from the fish tank?
Probably not a good idea as it will disturb the solids some what.
A small DIY canister filter would be what I recommend Jim. ua-cam.com/video/HtMZRM3a5Fs/v-deo.html
Hope that helps some.
I get those 200lt drums free. Could I put 2 radial flow filters in line to achieve a greater retention time?
My guess is that you would see more benefit from putting the filters in parallel. Retention time is basically a measure of upwelling speed, which you want as slow as possible in order to allow the finer particles, which have lower settling velocity, time to fall out.
Splitting the flow to reduce the velocity as TG mentioned above would be the way to go I think mate. 👍

Hi Rob, I'm yet too setup a small aquaponics system here and confused by to many reference. Should the water pass through biofilter bed (grow bed) and then to the deep water culture or can i bypass the grow bed and flow water to DWC?
You can bypass the grow bed if you think you have adequate solids filtration Mandan. It's best to remove as much solids as you can before adding the water to the DWC.
@@RobsAquaponics thanks Rob, that pretty much clears my doubt.
Is it possible to set up simple/reliable hydro/aqua system that will hum along without daily intervention when I take off and hit the road for a few months of vacation travel?
Quite possible but plant selection would be key. A lot of leafy greens are fast growers so may be finished before you get back. You'd also need to automate the nutrient dosing & water control as well.
On the retention time: Could you run three of the 200L (600L total) barrels in parallel and still have the same effect as one 600L barrel?
That would help a lot Brad. 👍 You looking at adding additional settlers?

Hi Rob thanks for the clip ! Rob can a person plumb 3 ibc's into one settler? And also I have found abs fittings and pipe are alot more affordable /avaliable thanks Rob
You can but it will reduce the retention time which in turn will mean a lot less solids will be captured for removal later George. If the settler was 500+L/130+gal it may do an OK job.

Great stuff as always Rob! One idea, could you not do a T-split from the SLO and into 2 X 200L settlers for a cheap 12min retention time? :) (as an alternative to a really expensive 500L version). Also love the idea of the “fork” water outtake for the settler to slow it down. Might need to play around with that idea myself :D
A few folks have suggested that & it would increase the RT dramatically.👍 Helps if you have the space to be able to set it up & would work out a lot cheaper than a larger single tank.
Hope the build goes well. 👍
Rob Bob's Aquaponics & Backyard Farm also worth keeping in mind that if your plants are already happy, maybe the double maintenance and space is not worth it, even if it is a cheap solution :)
