Dymax Bio Sponge 32 x 12cm

The Dymax Bio Sponge is a 32 x 12cm filter sponge that traps debris and gives beneficial bacteria a surface to grow on. It provides both mechanical and biological filtration for cleaner aquarium water, and can be cut to fit your filter.

Cutting and fitting it

Measure the compartment in your filter before cutting and trim the sponge slightly oversize, so it sits snugly and water cannot slip around the edges unfiltered. A long, sharp bread knife or strong scissors gives the cleanest edge, and offcuts can be used to cover an intake pipe in a tank with fry or shrimp. When an old sponge needs replacing, avoid changing all the filter media at once; instead run the new piece alongside the old one for a few weeks so the beneficial bacteria can move across.

Good to know

Rinse the sponge in old tank water rather than tap water to keep its bacteria alive.
