Eheim AKTIV activated carbon 250ml 140g

Eheim AKTIV is activated pelleted filter carbon for clarifying and chemically filtering aquarium water. AKTIV is acid washed and activated for automatic water adsorption (active surface area 1200 m2/g). It is great for removing substances such as chlorine, treatment residues and dyes. The water in the aquarium will then turn crystal clear. Its use is particularly important after treating livestock with medications. Can be used in external canister, sump, and some internal filters. Eheim AKTIV can be used in both freshwater and marine aquariums.
