The fine JUWEL filter foam is primarily used for the biological filtration of your aquarium and is therefore an essential component of the JUWEL filter system.
The fine-pored structure provides an extremely large surface area and guarantees a slow and even flow. This makes this foam particularly suitable for filtration in an anaerobic environment.
The open pores of the JUWEL filter foam are produced without the use of chemicals and therefore residue-free.
Properties of JUWEL filter foam fine:
Excellent biological filtration properties
