PetSmart OASE BioMaster 350 External Filter - Up To 90 Gallons

The BioMaster line of premium external filters is perfect for marine and freshwater aquariums. This filter 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. Water is first directed through the pre-filter's activated carbon foams which remove toxins and odors, then into the main chamber with filter foams of differing pore densities and Hel-x Biomedia - all providing surface area ideal for the settlement of beneficial bacteria. The BioMaster filters are engineered with integrated safety locking features on the handle, pre-filter, and check valve in the inlet/outlet connection unit, ensuring no accidental spillage or messy maintenance. The EasyClean pre-filter can be removed and cleaned separately from the rest of the filter. Designed using German engineering and manufactured in Italy, this energy efficient filter isbacked by a 3 year warranty that includes a free 1 year warranty extension with online product registration.
