Eheim Aquarium filter accessories Biomech 5L

Mechanical and biological filtration substrate for the simultaneous treatment of water. bioMECH is cleverly designed: dirt is captured in the pockets, whether it be fine or coarse particles. At the same time, the porous structure of this filtration substrate allows for colonisation by cleaning bacteria, ensuring reliable biological degradation. The material has a neutral pH and contains no hardness agents. EHEIM bioMECH is suitable for freshwater and seawater and can be reused multiple times.
