Fish Mate 20000 / 30000 Gravity Filter Replacement Foam

Choose the spare to match the filter

Replacement foam for the Fish Mate 20000 / 30000 gravity filter range. Choose it when worn filter foam no longer holds its shape or cannot be cleaned effectively.

Check compatibility before fitting

Gravity-filter foam and the cylindrical foam used in some pressurised filters are not automatically interchangeable. Match your filter label and compare the original foam’s profile, dimensions and any openings. Contact us if you need the supplied pack contents confirmed before ordering.

Prepare the filter for maintenance

Switch off and isolate the pump, UV and any other electrical equipment before opening the installation. Follow the instructions for your filter and keep electrical connections dry. Keep reusable parts together and inspect the housing, seals and fittings as you dismantle them.

Care for established filtration

During routine cleaning, gently rinse reusable foam in water removed from the pond rather than chlorinated tap water. Avoid replacing all mature biological media at once unless it is physically failing; established media supports the beneficial bacteria in the filter.

Fit the new part in the same position as the original and reassemble the unit as directed by its manufacturer. Check the flow and inspect for leaks after restarting. For other equipment, browse our pond filters and spares.
