Aquarium Filter Materials

Replacement foams, carbon and filter media for OASE and Superfish aquarium filters. First choose the exact model of your filter (BioMaster, BioStyle, BioPlus, FiltoSmart, Eco Flow…), then the foam grade in ppi.

How to choose the right filter medium?

• Model: each foam is cut for a specific filter; check the reference.
• Grade: 20 ppi for a coarse mesh, 30 to 45 ppi medium, 60 ppi for fine filtration.
• Carbon: it retains certain dissolved substances; remove it during a water treatment.
• Replacement: don't change all the foams at once, to preserve the bacteria.
