OASE BioMaster 250 Canister Filter

BioMaster 250/350/600/850

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

Fresh and marine water compatible
UL certified filter

The BioMaster series comes with 45 ppi activated carbon filters inside the pre-filter module. To optimize filtration OASE offers coarse 30 ppi, fine 45 ppi, and ultra-fine 60 ppi replacement foams to customize the pre-filter. All replacement pre-filter foams come in sets of six for your replenishment needs. Timing to replace the pre-filter foams varies upon aquarium size, number of fish and plants, and declines in filter performance. All BioMaster filter foams are compatible with any of the BioMaster models.
