BioMaster Thermo 250

  • 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
