Juwel bioPlusPrimo 60/70 Fine Filter Sponge - 1 Pack for Aquarium Filtration - Perfect for Freshwater and Saltwater Fish Tanks

UWEL Bioplus Primo 60-70 Filter Sponge, Fine

The JUWEL filter sponge coarse filters an aquarium via mechanical and biological action, making it an essential component of the JUWEL filter system. The coarse pore structure has a large surface area, which promotes relatively high and even water flow velocity. This means that it is particularly suited to biological filtering in aerobic areas. The open pores of the JUWEL filter sponge are made without the use of chemicals, meaning that there is no residue.

• Porous sponge filter media
