The external filter Oase BioMaster meets the highest demands for water filtration and filter cleaning. The combination of highly effective biological filtration by Hel-X and mechanical-biological cleaning by filter sponges ensures healthy and clear aquarium water. The EasyClean pre-filtration chamber allows convenient filter cleaning. The Oase BioMaster is suitable for aquariums with a maximum volume of 850 l. The adjustable heater Oase HeatUp can be easily retrofitted if required.

For initial setup and maintenance, we have written a helpful article in our Aquascaping-Wiki in German language.

Optionally, the pre-filter sponges can be upgraded to 30 ppi or 60 ppi subsequently. The other filter media can also be exchanged if required.
