Aquaponics is a technique enabling the sustainable production of edible fish and plants in a re-circulating system. Fish waste acts as a natural fertiliser, the plants absorb these nutrients, and the water remains clean and stable for fish. The only input is food for the fish.

Water from the fish tank is pumped into the grow beds and solid waste is removed by the addition of filter media at the water exit points. The water then travels through the plant grow beds where plants uptake the nutrients, and the water returns, purified, to the fish tank. The grow beds become a natural biofilter for bacteria to convert fish waste into accessible nutrients for plants.
