Ziss ZBS-150F Moving Bed Filter

An internal moving bed filter features self-cleaning media that provides a large surface area for beneficial bacteria. The water is initially filtered through a coarse sponge filter located at the bottom of the unit. It then flows into the main chamber, where the ZM-II media is constantly tumbled. This tumbling action allows old bacteria to detach from the media, creating space for a new generation of beneficial bacteria to thrive. 
The F series Ziss Filters include two suction cups, allowing the unit to be securely attached to the glass of the aquarium. Additionally, the top of the filter has a movable chimney that allows you to direct the airflow in your desired direction.

The unit comes with a Ziss ZV-4 Air Valve to control the air flow.
