FishFish excrete ammonia and carbon dioxide as byproducts of metabolism. In excess, these compounds are toxic to fish, however, are essential in the aquaponics system. |

PlantsPlants convert light and nutrients in to vegetation. While almost any plant can work (tomatoes from our system shown here), greens are ideally suited to aquaponics setups. |
BacteriaThe unseen heroes of the aquaponics system are the host of nitrifying bacteria. There are several types of bacteria needed to make the system work. These bacteria are not harmful, and in fact, are naturally occurring in the air, soil, and water. The system depends on the bacteria to change the ammonia from the fish into nitrites and finally into nitrates the plants can use. |

LightAt the heart of all biological systems on Earth is the Sun. Light is a source of energy allowing plants to grow. Light is especially important to indoor aquaponics systems. Certain plants rely on specific cues from the sun to know when to reproduce and grow. |
