This coarse foam sheet is for aquarists and pond keepers who need a trimmable mechanical and biological filter medium. It comes as a 25 x 25 x 5 cm block that can be cut down to fit the chamber of a given filter.
Why it matters
- Trimmable format: the 25 x 25 x 5 cm sheet can be cut to the dimensions of your filter compartment.
- Coarse 15 PPI structure: the 15 pores per inch density captures larger debris before it reaches finer media.
- Mechanical and biological function: the sponge traps particles and provides surface area for nitrifying bacteria, which support the nitrogen cycle.
- Wide water type range: the supplier states it is suitable for both freshwater and marine systems and for aquarium and pond filters.
