Adsorptive filter media
To adsorb means to take up onto a surface (as opposed to absorb = to take in). Adsorptive filter media are thus materials, which extract harmful substances from the water and attach or retain them. These substances are, for instance, chlorine in mains water, residues of water treatments or traces of cleaning agents, pesticides, colourants etc.
Filter carbon for clear aquarium water – especially for new tank installations
EHEIM KARBON is particularly suitable for water purification during the set-up phase of the aquarium. In particular, chlorine from mains water and other chemical substances, which can get into the aquarium during installation, are safely taken up.
EHEIM KARBON should be used for a short time (ca. 4 weeks) in the layering set-up after the mechanical (e.g. EHEIM MECH or MECHpro) and the biological filter media (e.g. EHEIM SUBSTRATpro) in the net bag provided.
* Binds chlorine and other chemical substances
* Use e.g. during set-up or after treatment with medications
* Use for a short period (ca. 4 weeks)
* Only suitable for fresh water
Only use adsorptive filter media for a few weeks, as the harmful substances are only attached and can loosen after some time and be reintroduced into the water. At the very least they should be changed regularly. Normally adsorptive filtration is only necessary during aquarium set-up or after treatments with medications.
