I don't know if this is the most active hydroponic forum but it coulld be a good start.
Hydroponics - GardenWeb
The thing with hydro is with all the air, water, nutrients and light mixed together it could be a breeding ground for fungus and algae. I actually grew a few pepper plants in a drip system but that was a few years ago and I forgot most of what I learned. I do however remember I dosed about 5 ml of H202 to keep algae fungus from starting. That might be counterintuitive with the ponds bio-cycle. Sounds like a good idea and you might be onto something.
Anyway, I just thought I post a link and give you a free bump
Good luck
