Filter sponges are the core elements of any filter system. Various microorganisms colonise them, converting harmful nutrients into nitrate for your pond plants. Our filter sponges have uniform pore sizes. This ensures a constant and even water flow. All sponges are suitable for ponds stocked with fish. Despite their long service life, they need to be replaced regularly so that the respective filters can work at full capacity.
