Aquaponics is a combination term of aquaculture and hydroponics and is the simultaneous production system of fish and vegetables without wastewater. In aquaculture, the water quickly becomes nutrient rich due to the fish digesting their food and excreting waste. In hydroponics, nutrient solution is required for growing plants. In aquaponics, the fish waste provides a food source for the growing plants and the plants provide a natural filter for the fish. This creates a small ecosystem where both plants and fish can thrive. In this study, for the development of a small aquaponics system which is enjoyable in a home or a school classroom, the completion of nitrification cycle and the adjustment of pH and ions in a short period were tried. The effect of microelements to the hydroponics also has been studied in the operation of aquaponics system.
