Description:

  • 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 400 adjustable heater into the BioMaster canister (HeatUp not included)

  • Made in Italy, backed by German engineering
  • Fresh and marine water compatible
