External Aquarium Filter - For the Highest Demands

  • 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)

  • What’s in the Box - Aquarium Filter, filter media, intake tube with inlet strainer, water distributor nozzle, spray bar, inlet and outlet adapters with flow control, tubing, fittings, heater adapter, and power cable
