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

Tip: 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.

Freshness & Storage

Every batch we dispatch carries a minimum of 6 months’ remaining shelf life. Store this product in a cool, dry place away from direct sunlight, with the cap or inner foil closed tightly after each use.

Filter media and substrates carry no manufacturing or expiry date — their working life begins on first contact with water, not on the shelf.
