aquarium pump shelf
Anyone in hydroponics using an aquarium with fish feces for fertilizer?

I have a 300 gallon aquarium in my greenhouse with trout and perch on it, and hydroponics shelves above it. The shelves are irrigated by pumping water from the tank to the upper platform, and that drains through shelves back into the aquarium, and plants on the shelves of fish waste as fertilizer and water is clean. What plants will be good on the shelves the best way to filter the water?

I wish I knew. That sounds like an awesome setup. If you have any specialized local fish place (not the chain), which would be a good idea to ask there. You may be given recommendations and supplies.
