The Oase BioMaster 2 is the latest innovation in Oase aquarium filters and has been completely redesigned to meet the highest standards. With the proven EasyClean pre-filter module, cleaning the BioMaster 2 remains extremely easy and offers maximum convenience for aquarium owners. The carefully coordinated combination of highly effective biological filtration through Hel-X and mechanical-biological cleaning through filter sponges ensures healthy and clear aquarium water.

The BioMaster 2 filter impresses with optimized water-conducting elements with an increased diameter. A new inlet and outlet as well as an innovative pre-filter inlet contribute to the impressive performance of this filter. Thanks to the revised geometry, the external filter runs particularly quietly and does not disturb fish or aquarium viewers.

With up to 25% higher flow rate compared to the previous model, the BioMaster 2 offers powerful and efficient filtration. The optimized energy consumption during operation and the high filter volume make the BioMaster 2 the ideal choice.
