Biozym Pond Filter Cleaner is a 500g biological treatment that breaks down organic waste in koi ponds, reduces filter load and promotes the nitrifying bacteria your setup depends on.

Filters slow down as sludge builds up inside — pond filters do the same job as aquarium and fish tank filters, trapping waste — and this cleaner sends biological agents in to break that waste down, restoring flow and cutting the time spent on manual clean-outs.
