EHEIM activated carbon pad (3 pcs.) f. classic 600

Fine and coarse activated
carbon filter pads for adsorptive filtration

For adsorptive filtration -
also for removal of harmful chemical substances (chlorine, remains of medical
treatments etc.) - there are special activated carbon fine and coarse filter
pads as a filter insert. Adsorptive filtration is usually only necessary in the
start-up phase of the aquariums or after use of medication. The filter media
should only be used for a short time (ca. 4 weeks) and then removed or replaced.
