External aquarium filter for the highest demands.

The BioMaster line of premium external filters boasts 4-stage filtration and is designed with sealed filtration pathways to ensure water travels the most efficient path through all filter media – creating optimal water quality and clarity.

Product characteristics

• EasyClean pre-filter module – Module can be removed separately from the rest of the filter. This reduces maintenance, increases filter efficiency, and extends the life of main filter foams. Customize the pre-filter with coarse 30 ppi, fine 45 ppi, ultra-fine 60 ppi, and activated carbon 45 ppi filter foams.
• No mess maintenance – Integrated safety locking features on the handle, pre-filter, and check valve in the inlet/outlet connection unit, ensure no accidental spillage or messy maintenance.
• Sealed filtration pathways – Allows for the full benefits of all four stages of filtration through this intuitive design.
• Hel-X Biomedia – An extremely large protected settlement surface (800m²/1000 liter) that allows beneficial bacteria to grow and thrive. The material is designed to stop floating as soon as it reaches a certain level of bacteria colonization.
• Carbon pre-filter foams – Activated carbon absorbs unwanted substances in aquarium water. Carbon filter foams make replacement much simpler than using common granular carbon.
• Adjustable flow control – Flow can be adjusted for the inlet and outlet in multiple locations on the filter assembly.
• Easy priming – Includes simple priming for fast and easy startup and continued operation.
• Quiet operation – Sound dampening design.
• Heater integration capability – Easily integrate an OASE HeatUp adjustable heater into the BioMaster canister (HeatUp not included).
