Eheim Ehfifix Mechanical Filter Media - 5 L

2-10 Days 

This special structured coarse filter material is used for mechanical treatment of the water and is used downstream of a layer of Eheim Mech. Eheim Fix is used as a parting layer between the mechanical and biological filter medium. Coarser particles are restrained and are thus removed from the water prior to entry into the biologically acting filter layers.
