EHEIM active filter media for external filters

EHEIM AKTIV is a special activated carbon with high efficiency, especially after treatment with medication. Eheim Aktiv is acid-washed and activated for automatic water absorption (active surface 1200 m²/g). As a result, this activated carbon binds chemical pollutants such as chlorine, pesticides, drug residues and other substances quickly and in large quantities. The water in the aquarium becomes crystal clear.
The use of EHEIM AKTIV is particularly important after setting up a new aquarium or after treating the aquarium inhabitants with medication.
It is suitable for both fresh and salt water.
EHEIM AKTIV is available in two packaging sizes: 250 ml and 1 liter.
EHEIM AKTIV belongs to the adsorptive filter media. Only use adsorptive filter media for about 4 weeks. As the pollutants only adhere, they can dissolve again after some time and return to the water. Regular replacement is therefore necessary. Adsorptive filtration is only necessary during the running-in phase of the aquarium or after the use of medication.
