I'm interested but I didn't have anything to contribute. I have several fish ponds and a couple of years ago I decided to try growing tomatoes in the filter of one on the roof. They didn't do well, they didn't die but they didn't thrive and I eventually took pity on them and planted them in a pot. I don't think I have a large enough fish load for the water plants and additional plants. I have only small tropical fish in the pond. When I tried my experiment I was doing a lot of reading about Australian aquaponics, it seems to be pretty big down there, and was really fascinated by the set ups I saw. I don't want to harvest fish so I wasn't interested in the tilapia that most of them use. I could use koi as they produce a lot of waste but I live close to the coast and don't want sea birds hunting on my roof. I gave up but it is still in the back of my mind as the perfect circle of food production, I would love to get it working some day. Anyway, I'm interested in any updates and pictures and I'll bet there are other lurkers as well. Good work.
