EHEIM filter medias are some of the best in the world. They are highly efficient, developed in their own research laboratories, and made from the best raw materials. They are continually checked and are guaranteed to be free from any harmful substances.
Eheim ‘activated’ carbon is an adsorptive-type filter media, which extracts and binds harmful substances and pollutants from the water.
These substances include:
treatment and medication residues,
tannins, (leeching from aquarium wood),
yellow or brown tints in the water,
Eheim ‘activated’ carbon will be effective at retaining these impurities in your filter for up to 4 weeks. After this time, the carbon will need replacing. Failure to remove the carbon may result in some of what has been removed being leached back into the aquarium.
This is particularly suitable for water purification during the set-up phase of an aquarium. It will ‘clean up’ the water, making it suitable and safe for aquatic inhabitants.
Another time for using carbon is if you have added some wood to your aquarium and the water goes a little cloudy. The carbon will remove this colouration but be patient as the woods can continue to leach the tannins for quite a while.
Eheim carbon does not remove ammonia, nitrite, nitrate, or phosphate. Do not use or remove when using the following:
fish disease treatments,
liquid fish food supplements such as vitamin boosters,
catappa or other conditioning leaves,
black water tonic, liquid catappa or other similar water conditioners,
Eheim carbon is pH neutral and contains no phosphates so it is perfectly safe and will not alter any of the water parameters in the aquarium.
Inside external filters, Eheim carbon should be used for only a short time (4 weeks). It needs to be placed in the layering set up of the filter after the mechanical (i.e. Eheim MECH or MECHpro) and the biological filter media (Eheim SUBSTRATpro). Place some Eheim SYNTH or an Eheim fine filter pad (white coloured) directly after the carbon. This will give the water that final ‘polish’ before it re-enters the aquarium.
Eheim ‘activated’ carbon cartridges and pads are suitable for both freshwater and marine aquariums. After the packaging has been opened, any new or unused cartridges and pads should be kept in an airtight container to keep the product in its best possible condition for future use.
Replace or remove after for 4 weeks.
