STANDARD SPONGE FINE L
The JUWEL filter sponge fine is primarily used for the biological filtering 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 filtering in the anaerobic zone.
The open pores of the JUWEL filter sponge are produced without the use of chemicals and are therefore residue-free.
Properties of the JUWEL fine filter sponge:
• Excellent mechanical and biological filter properties
• Homogeneous structure ensures uniform flow
• No chemical residues
• Suitable for fresh and salt water
