JBL Symec Filter floss

Product information

Filter materials serve multiple purposes: They either filter suspended matter out of the water (mechanical filtering), provide settlement space for bacteria that break down pollutants (biological filtering), or remove harmful substances from the water (chemical/absorptive filter materials).
The filter material should always be fitted from coarse to fine inside the filter, as fine filter material clogs too quickly at the beginning.
A coarse filter sponge or filter ceramic.
Filter floss should be used as the last filter material in external filters so that it does not get dirty too quickly.
Only in multi-chamber biofilters can filter floss also be used as the first medium, as it is visible there and can be replaced in a few minutes. Filter floss cannot simply be washed out and should always be replaced during filter cleaning.
Absolutely safe No pollutants released into the aquarium due to residue-free floss
