An air pump pushes air into the water through a diffuser. The bubbles stir the surface and raise the dissolved oxygen, which benefits the fish, the bacteria in the filter and the plant roots. Choose the output according to the volume of water: allow a pump delivering a few hundred litres of air per hour for an aquarium or a grow tank, and several thousand for a well-stocked pond or a production aquaponic system.
A battery backup pump takes over during a power cut, and a solar pump aerates a pond far from any socket. Add air stones and aeration accessories that fit the pump's tubing.
