Oase BioMaster Carbon Prefilter Foam

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 four or 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.

Activated carbon absorbs unwanted substances in aquarium water.

Carbon filter foams make replacement much simpler than common granular forms.
