Oase Biomaster 250 350 600 850

The OASE BioMaster series is an externally mounted aquarium filter with integral powerful pump. The filter is designed for fresh water or marine aquariums from up to 250L - 850L. The BioMaster is designed and engineered in Germany and is packed with innovations to make the task of aquarium filtering as simple and efficient as possible.

The EasyClean pre-filter section can be simply removed for cleaning without the need to disconnect hoses and also features a robust built-in priming button for fast start up after cleaning or upon installation. The BioMaster also contains a series of fine and coarse filter sponges mounted inside the main filter section and 2 layers of OASE Hel-X 13 BioMedia. The combination of foams and bio-media offer superb mechanical and biological filtration and the main filter segment requires infrequent maintenance, thanks to the EasyClean Prefilter.
