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.

The BioMaster canister filter family is characterized by high filter performances and long service lives. The EasyClean features and advanced designs are perfect for maintaining a clean and healthy ecosystem for your fish and plants. The Thermo line has the added feature of an integrated heater. By integrating the heater into the filter, the amount of additional equipment seen in the aquarium is reduced.



  • Integrated heater – Provides precise and uniform temperature levels and reduces the amount of equipment seen inside the aquarium by housing the heater in the unit
  • 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
  • Ideal for use in aquariums up to 225 gallons
  • Made in Italy, backed by German engineering
  • Fresh and marine water compatible
  • UL certified filter, UL certified heater
  • 3 year warranty plus 1 year warranty extension with online registration
