Pontec Replacement Foam Set for the Biopress 4000

This Pontec Replacement Foam Set is the genuine consumable for the Biopress 4000 pressure filter, returning your filtration to full performance once the original foams have compacted or worn. In Singapore’s warm climate, foams clog faster than in cooler countries because biological activity and algae growth run year-round, so keeping a spare set on hand means you are never caught with reduced flow during a green-water bloom or after heavy monsoon runoff loads the pond.

When you swap foams, rinse the new pieces and stage the change so you do not strip out all your established biological bacteria at once; ideally replace one section at a time across a couple of weeks. Always rinse media in dechlorinated or old pond water rather than chlorinated tap, which kills the beneficial colony. Restoring fresh foam improves both mechanical capture of fine debris and the surface area that drives biological filtration, keeping water clear and fish healthy.
