In aquaponics, the water is recirculated from a fish tank through a vegetable grow bed. the nutrients from the fish waste feed the plants and the plants filters the water and keep the fishes healthy. the two main components of an aquaponics system are the grow beds and the fish tank, which are connected via a small pump that moves the water between them.. The key to aquaponics is the natural bacteria found in the growing bed (called the biofilter) . the bacteria eat ammonia and turn it into nitrates, which are great food for plants. without these nitrifying bacteria, the fish would die in their own waste. without the nitrates, the plants wouldn’t have anything to eat.. In the 1980’s, mark mcmurtry and doug sanders successfully designed the first known closed loop aquaponic system, in which water from fish tanks irrigated cucumbers and tomatoes in grow beds with sand medium – the sand also worked as a bio-filter; the filter water was recirculated into fish tanks..
