Juwel bioPlus coarse M filter sponge

The Juwel coarse filter sponge is used for the mechanical and biological filtration of your aquarium and is therefore an essential component of the JUWEL filter system.

The coarse pore structure provides a large surface area and ensures a comparatively high and even flow rate of the water. This makes it particularly suitable for biological filtration in the aerobic range.

The open pores of the Juwel filter sponge are achieved without the use of chemicals and are therefore residue-free.
