Oase BioCompact 25 Spare Parts Explained

Keeping genuine spare parts on hand for your Oase BioCompact 25 internal filter is the simplest way to keep it running quietly and efficiently. Internal filters do a lot of work in the warm, biologically active tanks we keep in Singapore, where heavy feeding and 27-29C temperatures mean media and seals see plenty of use. Replacing the right component, rather than the whole unit, keeps your beneficial bacteria colony intact and saves money over the long run.

When you order spares, match the part to your exact model so impellers, foams, and seals fit correctly and the filter primes properly. We always advise rinsing replacement foams and biological media in old tank water, never under the tap, so you do not wipe out the bacteria that drive your filtration. After a power outage, check that the impeller spins freely and the filter restarts cleanly before assuming it has failed.
