PREFILTER SPONGE FOR ALL FZN PRO

Replacement filters are a ready-made solution that will improve the care of clean aquarium water. A profiler plays a special role in removing unwanted substances from the water. It enhances the work of the main filter materials and ensures that larger impurities will not penetrate further. In the FZN PRO cascade filter, the function of the profiler is performed by fine elements of coarse filter sponge.

Their cylindrical shape allows you to optimally use the filtering surface, as well as to fill the basket correctly. The sponges should be placed in the container located under the adjustment knob.
