Juwel bioPlus fine M fine-pored filter sponge

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

The fine pore structure provides a very large surface area and ensures a slow and even flow. This makes it particularly suitable for biological filtration in the anaerobic range.

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