Notice the plants floating on the tank surfaces, and the pipes between tanks. Both work to keep the water clean. The plants take up fish waste through their roots. water from the tanks will cycle through filters and pH-balancing media (gravel or shell).

Inside The Ark

What do you want? What do you have? These are fiberglass tanks -- about adult human height -- full of fish. Humans dump in grass clippings, and grass carp eat that. Algae grows on fish manure, and tilapia eat the algae, while mirror carp keep things stirred up. Maybe there are some bluegills to get rid of any hungry baby fish the others might pop out. Protein for crap! This 35-year old picture of ecological food production is from the New Alchemy Institute.
