Fish2Food Backyard Mini-Farm Aquaponics Tour and Systems. Aquaponics is a sustainable method of farming crops and fish symbiotically offering higher yields than with crops grown in soil and in less time. The fish poop and decomposing matter is converted into nitrites then into nitrates in the growbeds. Nitrates feed the plants and the clean water is returned to the fish tank thus completing the Nitrogen Cycle. We have four systems available for purchase and we can ship to your location or we do installations within 75 miles of Orlando. We are also trained in Commercial Aquaponics Applications and have several commercial diagrams that are customizable to your needs.
