“Perhaps the most interesting, however, is the completely closed-loop urban food growing system – the Inka Sun Curve. The fish in the tank need oxygenated, clean water. The water from the tank is pumped up through the system and the roots of the plants act as a biofilter to help clean the water. As it drips through the system and back into the tank, it puts more oxygen into the water for the fish.

With aquaponics, the fish poop acts like fertilizer for the plants so the plants naturally get the nutrients they need. While fish naturally produce ammonia which isn’t something plants can use, by putting certain microorganisms into the grow media, the ammonia is turned into nutrients the plants love.”
