    Oase BioMaster Thermo 250 External Aquarium Filter
    Ideal for use in aquariums up to 70 gallons.

    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

    Fresh and marine
