Sounds like you know what it takes madds but im sure bb does more that allot of other people out there. I too have too much time on my hands but with low funds its kinda hard to keep a nice grow room running. Glad the fish are still alive, I have seen vids on youtube of some greenhouse grow with normal plants lol that have their hydro flood table hooked to a hug res containing fish that receive light from the sun. I guess the fish feed on alge and create some kinda kelp guano mix along with other stuff. Its pretty cool and similar to what your trying to do I guess, If I find it I'll send you a link.
