d neckel: What do you do in the winter? Do you have to shut down the system?
Talzhemir Mrr: Much better than electrical filtering, use tilapia fry. They're
micro-algae eaters. They'll turn a mucky fish tank clear. Their droppings
are dense and encourage the kind of algae that grows like tiny grass on the
bottom, which is nutrient-rich food.
Wilson Pellot: I built an aquaponic system similar to this one. I had some trouble with
the syphon. It worked well without the media but once I put the growing
media in fill and drain times were reduced. What I found to work best for
small grow beds is to reduce the pipe on bottom to a 1/2 inch pipe. Then
you don't have to worry much about drops, elbow, 45deg.... I was able to
tune it down to a trickle. Fills and drains in 18min. So a little over
three times per hr. Hope this helps. Happy Gardening.
Also because these concrete mixing trays are weak it's best to have them
sit on a 1/2 in plywood. This keeps the bottom from bowing and the bell
syphon level. Don't get too creative. Simplicity is the key to success
with these systems.
Tiersmoke92555: Copy-kat!!! Have you been looking in my back yard??? Your setup looks a
little neater the only thing that was new in my rig is the mixing tub. I
will be adding a jug swirl filter to help with pooh build up.
Jaimie McCallum: Absolutely love your system. I am going to try and replicate it once I move
down to Georgia in January! Going to build an Earth Bag home and an
Aquaponics system! Goals!!
Charlotte Alexander: I keep thinking about Rain and and how,if at all,it will have to be dealt
with using an outdoor Aquaponic system.
Lee Ralph: Hello,
I remember watching this about 1 1/2 ago, but never got into aquaponics. I
am wanting to get into it now, is there anything that you would do
different now? Are these food grade? and does that matter?
Thanks for the help, Lee
James Wang: Hi
I made a bell siphon after watching your video and I am using a cement
mixing tub as a grow bed to hold media. The pond I have is a 140g and pump
is a 200something GPH from Home Depot.
When I first made the aquaponics system, the siphon was not getting started
correctly so I adjusted the distance between bell and the stand pipe. Then
I found out that the bell itself was not staying down to the bottom of the
tub because the bottom was somewhat warped.
Once I put in the substrates (Hydroton), it seems to have helped the
problem as the siphon ran correctly. However, everyday after I get home
from work, I would find the siphon just running and not stopping correctly.
I adjusted the flow rate to turn down the water going into the GB, and then
it would run normally.
Then, I decided to add some GrowStones into the GB so there would be more
weight. Again, the system will work throughout the night and even in the
morning and I would come home and find it not working. This morning as I
was adjusting the flow rate, I find that the siphon no longer even starts
(i was trying to push down the bell and the media guard to see if they
moved) and the water overflooded from the top. I shut off the siphon and I
will probably have to fix it later.
So my question is:
Do you guys think the media has something to do with it? WHen theres water
in there, most of the Hydrotons and evne growstones just float up, and I am
afraid some of it might have gotten inside the bell/media bc nothing is
being held down.
Do you guys think its the tub? its warped on the bottom so sometimes the
siphon is on the bottom sometimes its not, I feel like with the substrate /
water in there this should be a problem?
Any other recommendations? Please I need your advice as I am relatively new
at this. Thanks
nathan turner: nice little system , I would perhaps use some larger perforated tubing to
go over your syphon so when your stone is in ,the contact between syphon
and rock weight doesn't halt the progress of the syphon . also are you
using a bio filter to help transform your ammonia and nitrites into
Josh Campbell: What did you end up doing for the tub support system?
TheShirtAnPants: Can you include a supply list. I am brand new to this and want to build
your set up.
elizabeth french: I would really like the diy step by step
Ventarmy: Whats the best type of fish for this system if I was trying to grow some
tomatoes beans and other veggies?
Gladys Bach: *crazy gardening technique uses fish poo to grow organic food 4X faster*
Leslie Smith: Nice setup... $150 is not really close though. We have done the same
setup.. has cost about $500. The stock tank alone is $60-80, plus plumbing,
pump, bell siphons and clay media.
D Walks: What trays are you using for your grow bins? I see those a lot but I don't
know what they are.
jasonsaved: this is a neet little system, but i am going to worn you in advance that
one you get started you will not be satisfied untill your backyard looks
like a farmers market. Aquaponics is the best way to grow
1too3fore: Dude, that's not oxygenating the water, the bubbles are formed from the
water splashing. Still need to add an aeration system.
David Epstein: Nice setup, Next time you might want to tweek it with a Trickle Valve set
so you can have a longer flood time and greater distribution of nutrients.
Plus gives you a lot of versatility with techniques of NFT, Deep Water and
Flood Drain. Since you've got big beds you'll need a lot of rocks. A deep
water alternative might be cool.
Jeff DeBeck: Dear David I'd like to try what you've done with the 100 gallon tank and
two 15 gallon grow tanks. Where did you get your 100 gallon tank? Did you
set up a material list? Thanks, jeffdebeck@gmail,com.
Chris Scarff: You did this video 2 years ago, but I'm sure I'm not the only one looking
for your follow-up videos or even pics. Did you complete this project?
Are you still using it? Did you enlarge it? If so, how big? I just
purchased the same 100 Gal tub for $69 USD. I also purchased it's 50 Gal
sister tank for a large sump. I didn't like the look, nor the smell of the
grow-beds (looks the same as yours too), and there was no official recycle
symbol on them, so I had to go cheeper on the grow beds, for now, but they
looked be be better plastic (PP). Post some updates if you have them.
Thanks, good stuff.
Alex Stensland: What is a good time for syphon start to syphon start I just set my system
up and I am messing around with the flow rate
chefgiovanni: Very cool

Lacocacolaman: Isn't there a concern for BPAs and all the other stuff the plastic leaks
into the food?
sootedninjas: are the Parts list and specs available ?
DJ McBall: Would you have a materials list?
Geoffrey Wylie: I built a very similar system in my basement and wanted to ask how yours
was going. I have a few other questions I am still working out but did u
purify the water before putting in system? And is your pump constantly
filling and the siphon is draining ?
Awesome video thanks
J.R. Stinson: Really cool man. I am getting into AP growing and learning more as I go.
Any thoughts about doing a long inlet pipe with holes drilled so water can
more evenly distribute upon entry to the beds? Also, what about making
those syphon slits bigger to prevent clogging from algae? Also what type of
pump did you use? Model/make?
Thomas Pope: I am curious as to what your water Ph would be and I was also thinking a
timer on your pump would be a good idea. My experience with hydroponics is
that you don't need to flood (feed) the plants but about 4 times a day.
Those little clay rocks I forget what they are called, hold a lot of
moisture between feedings so I do not think your roots will dry out. Let me
know how you do. Also you may want to add a small air pump and bubbler
stone to add extra Oxygen to the "fish pond" fish love oxygen.
Cameron Caviness: I have a couple concerns:
1. For long term use I would highly recommend a form of mechanical and
- If the water is continuously unfiltered mechanically the build up of
feces and uneaten food will eventually stick to the roots of the plants and
clog them up of sorts. This can cause decreased efficiency in nutrient and
water uptake which can inhibit growth and eventually kill the plant. This
can also cause root rot - which in turn leads to plant death. I would
suggest either a radial flow filter or a swirl filter.
- Contrary to popular belief plants will not act as a complete filter to
remove all harmful dissolved gases from the water. The main one is ammonia
- plants do not like ammonia. I would suggest a bilogical filter with
colonized nitrobacter and nitrosomonas to effectively convert ammonia ->
nitrite -> nitrate. Without doing significant water changes at least once
per day ammonia would build up to a harmful level very easily.
2. I would suggest to completely cut out the water pump and try circulating
all of the water through an air lift. Small air pumps use less energy and
will also allow you to aerate the water if you wish to stock your tank at a
Overall it is a great design. I am by no means trying to bash the system,
just simply offering advice of ways to improve this system for long time
Karen Jernigan: do you have a list of materials?
I already have a pump, so I am wondering on other materials.
What type of fish are you going to grow?
Kevin Smith: Thanks for the idea. I am building a setup right now using this as my base
alphasxsignal: I like my vegs from good old dirt, not fish poo. YIKES
Only humans would think of this stuff.
massis32210: great job...keep it up...
Kwyeuht Storm: I truly want to make this.
Erik Mathew: With ocean fish being hunted to near extinction all because people don't
want to stop all for money this seems like a solution to a renewable fish
resource, the ocean fish can only populate so quickly
caldreamin09: Wow that's awesome!!! It finally hit me how the bell siphon works!! The
bell, or cap creates a pressurized environment which is broken when the
water goes down to the slots cut near the bottom of the pipe. It's
basically just an air bubble within a siphon.Thanks for the no frills
demonstration, it was very helpful
Jim Chen: how to you control over flow from rain when the system is outdoor?
Albert B: You need a 3rd bin involved that stages the water a little longer to clean
it and break down more fish waste. Otherwise, I think your going to end up
with dead fish. There are specific varieties that do that well. I think
bamboo is one, but a google search will tell you. Nice clean system though.
John Oliver: Brilliant!
Don Rogers: Very good have some thought in same area did short test run late last year
then revamped almost whole thing about to start again , ice took out two
large limbs which took out most of my system have new seedlings started and
about to start against. Have to finish two more grow beds
jerry innes: my system works just fine without a bell siphon... i would imagine that if
you have any plants near the siphon that the roots will grow into it and
cut off your drainage and empty out your main storage tank
Mh Fish: I am sad that your lovely aquaponics video opens with a pro oil ad.
otherwise thank you and great job!
Richard Claessens: you fill time drain time is just about right the beds should be higher
so the water can siphon more powerfull and that would also create more air
for the fish
make sure your fish are legal in your state ... use lots of fish about
1 gal / inch of fish let the fish "set the water for a few days then put
in your plants.
kevin barreto: here are the grow beds
Olen Soifer: This is a good start, but you're missing two major components: A solids
filter and/or a biological filter. If you use DWC, you need the bio filter
or your fish will self-destruct from their own ammonia waste. And, if you
use growing media & hope for it to be the bio filter also, but you don't
have a solids filter, the bed will end up clogged the solid fish wastes.
quickplaya: That will get covered in algae growth... good idea though.
