COMPACT FINE 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 offers a very large surface area and ensures a slow and smooth flow. This makes it particularly suitable for biological filtering in the anaerobic zone.
The open pores of the JUWEL filter sponge are made without the use of chemicals and are therefore free of residues.
Properties of the JUWEL fine filter sponge
• Excellent mechanical and biological filtration properties
• Homogeneous structure ensures uniform flow
• Without chemical residues
• Suitable for fresh and salt water
