The ASAP internal filter consists of a modern energy-efficient motor housed in an elegant casing and a large transparent filter container filled with selected filter sponge. The sponge quickly becomes inhabited by beneficial bacteria, so that the water passing through the filter undergoes biological and mechanical filtration.
The new ASAP internal filters are also suitable for use in terrariums, as they can operate in shallow waters as little as 5 centimeters deep. Additionally, they effectively channel water into the tank, causing a strong movement on the water surface.
