Air Powered Filters in Aquariums

Air Powered Filters are filters of small capacity which are ideal for small aquariums. These filters do not require any external power source. They are driven by the air flow from the pump.

The air is allowed to rise through a tube which drives the water upwards. This causes a suction effect in the bottom. The water from the surrounding areas enter the tube through a sponge which filters the water.

The sponge material also serves as a medium for the beneficial bacteria to grow. Thus, it also acts as a biological filter.
