Eheim bioMECH is a combined mechanical and biological filter media. It traps coarse and fine dirt particles, and at the same time the clever pore structure ensures the colonisation of friendly cleaning bacteria. This is particularly useful if media space is restricted, or you have a heavily stocked aquarium. Suitable for use in most external canister and sump filters.
Eheim bioMECH is made from a pH neutral material, is reusable and is suitable for both freshwater and marine aquariums.
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.
