OASE BioMaster External Canister Filter with Pre-Filter

The BioMaster is a workhorse external canister filter whose signature feature is the removable pre-filter module: a cartridge you can lift out and rinse on its own without opening the main canister. That means your biological media stays undisturbed and your bacterial colony intact during routine cleaning, which is exactly what keeps water parameters stable. Generous media baskets handle mechanical, biological and chemical stages for tanks across a wide size range.

In Singapore’s warm climate, fish feed and produce waste continuously, so a filter that makes frequent mechanical cleaning quick and low-stress is a genuine advantage; the pre-filter rinse takes minutes and spares you a full teardown. Position the canister in the cabinet with accessible hose runs, prime it fully before powering on, and rinse media in dechlorinated or tank water rather than chlorinated tap to protect the beneficial bacteria you depend on.
