A set of 6 blue replacement pre-filter foams for the Oase BioMaster canister filter. The blue foams are a finer pore density, polishing the water and offering more surface for beneficial bacteria as the pre-filter stage that protects your main media from clogging.
Pull and rinse the BioMaster pre-filter module without opening the canister; replace a foam when it's too worn to clean. PPI means "pores per inch" — the foam's pore density. Lower PPI is coarser (catches bigger debris, clogs slowly, great as a first/pre-filter stage); higher PPI is finer (polishes water and offers more bacterial surface area, but clogs faster).
