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.
massis32210: great job...keep it up...
John Oliver: Brilliant!
Patricia Shriver: how did you keep the connections from leaking? Every connection I have
leaks. I glued the hose to the pvc connection because it leaked really
bad, and it worked for about 36 hours, and is leaking again. Is it because
I don't have man-muscles?
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
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.
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?
alan spurlock: i really am really interested in aquaponics. however, it seems like there
is a lot of set up cost. i am not sure that the yield is any better than a
traditional garden. also, u have to pay the electricity for the pump. is
this all hype or fad? or am i missing something here?
jeremyhall420: I use two small solar panels charging 2 12v batteries in parallel that runs
my inverter setup and runs my pumps in my system. So the electricity is
free for my system.
namingsway: couldnt you just drill a few holes in the grow beds ? like maybe 5 small
ones in each ? that would cut costs in pvc pipe no ?
claudia gamino: How many pounds of hydroton do I need for a 15 us quart tote/container??
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
kevin barreto: here are the grow beds
Christopher Brignola: you should always test with media in the bed, when testing without the
timing and water amount will be off
Anthony Jimenez: that is GREAT!!!! I am getting into the same i have some land in colorado
and we are going to do this too.. THX for the info once again GREAT JOB!!!
FishNinjaY: excellent. I also liked your video specific about the Tips/Tricks of the
bell siphon. This is a nice system. Do you think your estimates on flow and
siphon function will change once you have the grow beds filled with media?
Seems like it shouldn't. Thanks! Subscribed.
Chris Bridges: When I was in Hawaii, i built almost the exact same setup. I used a round
pond liner fish tank. It worked very well, but your times are going to
change completely once you have the lava rock in it, so I wouldnt stress
about the times too much. You will be fiddling with it off and on for a
while. I know I did. I had to adjust the water flow once a week or so, as
algae built up in the supply line or the filter on the pump got dirty. I
figured out that most problems with my system cycling could be overcome
with increased water flow into it. So if it gets to be too much bother,
try moving up to a higher capacity pump. You may be able to find pictures
of my system on my google+ page if your interested. I made a great stand
for those two beds out of just 5 2x4 boards and some screws I had laying
around that was very sturdy. Nice job on the system.
Jenn Rebel: WOW! AMAZING! THANK YOU! GOING TO TRY THIS!
Benjamin Brown: Where did you get your grow beds? I have been looking all over for some
like that and can not seem to find them. My ap system has a complete cycle
every 15 mins. This is my first one, that seems to be doing fine for
germinating seeds as well as the mature green onions that I have in my
David Edlund: EVerything looks good. Stick with it. Remember that when you have the
hydroton, it will fill faster. Gj
Donnie Bennett: how is your system working for you?
steven baker: Two questions. What are you using for your beds? And do you run your pumps
kadmir2004: Great setup brother. Suggestion: Your drain and fill should be on a 1 hour
cycle. Your video said you have 8 minute fill and 4 minute drain. You
should be draining about once an hour to avoid root rot.
T25AM76: Great job. Does the fill and drain time reduce by half or more when the
grow beds have media in them? I guess it varies on how much volume the
media takes up and the fill and drain time reduces ?
1mtstewart: with your system, what is the pounds of fish/gallon to start/ end. what is
your grow bed size l x w x depth per gallon of tank water? have you tried a
floating or supported raft system, with net pots and clay balls instead of
rock or other media?
Thunder Wolf: I am looking for details about your products please leave message
Green Hands of Aloha: Aquaponics is liberty.
Development Services International: $150 aquaponics set-up. Only thing missing is fish, and bio-filters.
Otherwise, it's a basic system.
Donnie Bennett: we are looking to build a system and wanted to know of any changes you
might make with hindsight
Dewane Mong: no offense ,but i dont even get why ppl do small units like this....its
just a hobby costing you money.if you are harfesting 100 pounds of fish a
year and a 100 pounds of vegtables good for you....if not...its juist a
hobby costing you money
growownfood: Choosing a general design for your aquaponics garden is a choice.
John Miller: +Tracy Holz This guy had an interesting setup but I think I still like your
jon obrien: u gonna grow the lettuce in styrofoam ? use gravel?
stickypopful: perfect setup!
jon obrien: put airstones and a air pump in each 20gal resevoir
jon obrien: usde tilapia or koi
bluemoon1348: This is an excellent video, thanks for shareing!
Indoor Harvest Gardens: I built a platform for the grow beds that cover the fish tank. You can put
shade cloth over that so it only drips on it, then i moved it indoors. If
you left it outside and were worried about it you can add a overflow to the
fish tank so it doesn't just pour over the side with too much water. Many
customizations for whatever scenario.
Khyle J. Lewis: i have a friend in bangkok who knows plenty about this drop me a line
dilleetee: I'm looking at a lot of aquaponics start-up and I like the way you go about
your project. Thanks
Michael Tricker: More power to your elbow for building your own syphons. But for those who
are put of buy the thought of all the trial and error it is possible to buy
auto syphons on line from plumbing stores. They are generally used to flush
the urinals in gent toilets. They are cheap and very..very reliable. Check
ebay and amazon. Keep on growing. Regards mike
Indoor Harvest Gardens: yup, some people use a timer to stop it at night and then drill a small
hole in the bottom of the standpipe (so the water drains) but yes slower
fill, fast drain. thanks for watching ;)-
Ray Bright: Is there always some water in the bottom of this system? If so, how deep?
Selfsufficientrobinh: Hey, if you ever respond back cause I know most people don't even check
their comments... I have some ideas that would help your system out a ton!!
Just send back and we could talk and discuss different techniques and
methods on aquaponics
Fred Wright: how do you controll the water temprature. hot and cold? I live in Australia
and it gets prety hot in summer but also get cold at night in winter.
Ahmad Nassri: Am I wrong in thinking the ampunt of growing space is diproportional to the
amount pf fish space? I forgot what the numbers were, but there is a range
of square feet of grow space that should be available per unit of water
(and obviously a range of fish population per unit of water). If the system
doesn't have enough grow space not enough NO2 will be absorbed by the
plants and you'll end up with it accumulating over time and possibly
becoming dangerous to the fish.
Margaret Corbett: Ed, Thanks for your speedy reply!
zeekthe hammer: with your valves controlling your pump.. do u have a wild loop for the pump
in case both valves get shut? it will dead head the pump if there isnt
enough flow through your specifically designed pump as all pumps are..
william adams: Hey, I was wondering what kind of fitting you used to connect the rubber
hose to the PVC pipe. Because I'm trying to build my own, and I am just
wanting to find some different options before I spend the money for the
hose and fitting. Thanks.
S Hao: Thank you very much for your post. This is the perfect size that Iwas
looking to start my aquaponic system at. Is that the concrete mixing pan
your using for the grow bed? Where did you get your rubbermaid fish bucket
from? 400 gal sounds perfect. Thanks again.
