JUWEL Filter sponges BioPlus coarse

Juwel BioPlus coarse filter sponges are very important for the mechanical and biological filtration of your aquarium. They are an essential component of the JUWEL filter system. The large surface area and the coarse pore structure ensure a high and even flow rate of the water. The large surface area makes them particularly suitable for biological filtration in the aerobic range. The open pores of the Juwel BioPlus coarse filter sponges are achieved without the use of chemicals and are therefore free of residues. They are suitable for both fresh and salt water and can be easily cleaned under lukewarm tap water.
