oase aquarium filters: internal & external

OASE BioMaster and FiltoSmart external filters for aquariums, with or without built-in heater (Thermo), and their replacement foams. Choose by aquarium volume, whether you need a built-in heater and the space in the cabinet.

How to choose an OASE filter?

  • Volume: the number in the model name (250, 350, 600, 850 for BioMaster; 100, 200, 300 for FiltoSmart) is the target aquarium volume in litres.
  • Thermo: heater built into the filter, with no heater visible in the tank.
  • Range: BioMaster with an accessible pre-filter, FiltoSmart more compact.
  • Maintenance: keep the right replacement foams on hand (20, 30, 45 or 60 ppi).

Foudebassin helps you choose the filter best suited to your aquarium: aquascaping, freshwater, reef…
