Replacement Foam Set for the OASE FiltoClear 11000

The foam set is the working heart of a FiltoClear pressurised pond filter. It traps suspended debris mechanically while its enormous surface area hosts the beneficial bacteria that convert fish waste into harmless compounds. Over months of use those pores clog and the foam structure breaks down, so flow drops and biological capacity falls. Fitting fresh original foams returns the filter to its designed performance without you needing to upgrade the whole unit.

In Singapore’s year-round warmth, koi and pond fish feed and excrete heavily, so the bio-load on a pond filter never really pauses the way it might in a temperate winter. That steady demand means foams here work harder and benefit from periodic replacement. When you swap them, rinse the new set in dechlorinated water first, and avoid washing established media under chlorinated tap, which kills the bacterial colony you rely on.

We carry genuine OASE foams alongside our wider filter media selection. To understand how mechanical and biological stages work together, see our filter media guide and beneficial bacteria explainer before you service the unit.
