Aquaponics is a recirculating system that combines hydroponics (growing plants in a nutrient solution without soil) and aquaculture (fish farming) to create an efficient closed loop system:

  1. We feed the fish
  2. The fish poo
  3. The nutrient rich waste-water from the fish tanks is pumped to the roots of the plants where microbacteria convert the waste nutrients into helpful nutrients
  4. The nutrients fertilise the plants and in turn the plants purify the water
  5. The water is then pumped back into the fish tanks
