ML, with that kind of water, that explains alot. We rarely if ever see water very green less than 18 inches visibility unless we fertilize. You have some great water quality and I thnk the tilapia only help keep it that way. You have a great combo going and I see how heavy feeding it could cause a problem. Here if you want to get close to maximum carrying capacity we need to lime/fertilie and feed. thanks for reply.
