This aquaponic system uses a 20 watt 396gph waterpump. The fish tank is a standard 55 gallon drum under a frame made from 2"x3"s and some 1"x2"sand the gravel bed is a $12 water basin from Lowes.
It's a flood and drain using a Bell Siphon.
I built this last year and used it until mid fall and left it outside over inter and turned it back on after it was fully thawed this spring and it turned on without any problems.
We've been growing many types of lettuce, mustard greens and arugula in it. It's also being used as a cloning station for Thyme, Rosemary and Tomato plants. Last year we grew several tomato plants, a cucumber and a fist sized watermelon.
Oh, I need a cloning bed. Why didn't I connect those dots?. THANKS!!!

Currently, we have about 20-24 goldfish running this system. It was running on about 12 goldfish up until about 2 weeks ago, then I added about 12 more and the greens got greener. I think the plants enjoyed the nitrate boost.
