The ASAP internal filter consists of a modern energy-efficient motor housed in a sleek casing and a large transparent filter container filled with selected filter sponge. The sponge is quickly colonized by beneficial bacteria, so the water passing through the filter undergoes biological and mechanical filtration.
The new ASAP internal filters are also ideally suited for use in terrariums, as they can operate in shallow water depths of just 5 centimeters. Additionally, they effectively circulate the water in the tank, causing a strong movement of the water surface.
