Pond Boss Forums INTRO Questions & Observations Can talapia be raised above ground swimming pools?

Maybe I should go floating raft? I want to grow more than just lettuce and basil though... I think I'm going to have to have a low cost soil like material to do that. My six new fiberglass tanks are 8x17x2'. Gravel or floating-raft is the only affordable alternative to my knowledge. Volcanic gravel is my choice.
