Water from the fish tank is constantly pumped as much as a bio-reactor, which is a flowery phrase for a small filtration system that primarily homes micro organism; that micro organism converts ammonia from the fish waste into types of vitamins for crops; water exits the bio-reactor and is dispersed by trays housing crops, which take up the vitamins. The water then falls again into the fish tanks so clear that it makes for blissful, wholesome, hungry fish. We feed the fish and thereby maintain the entire cycle going.
