Symec Filter fleece

The JBL Symec Filter Fleece for Aquarium Filter fits into any filter. It catches tiny dirt particles and provides the filter bacteria with sufficient room for colonization.

Filter materials serve various purposes: They are intended to filter suspended matter out of the water (mechanical filtration), they are intended to provide habitat for pollutant-degrading bacteria (biological filtration) or they are intended to remove harmful substances from the water (chemical/absorbent filter materials). Of course, mechanical filter media also become biological filter materials after a certain time.

In the aquarium filter, filtering should always be done from coarse to fine, as fine filter material clogs up too quickly at the beginning.

Filter cotton should be used as the last filter material in external filters so that it does not become dirty too quickly. Filter cotton can only be used as the first medium in multi-chamber biofilters, as it is visible there and can be replaced in just a few minutes. Filter cotton cannot simply be washed out and should always be replaced when cleaning the filter.
