Eheim - FIX, Mechanical filter medium 1L

EHEIM FIX: Mechanical filter medium

This specially structured coarse filter material is used for mechanical treatment of the water and is "downstream" a layer of EHEIM MECH. EHEIM FIX is used as a separating layer between the mechanical and biological filter medium. Coarser particles are trapped and are thus removed from the water before entry into the biological filter layers. You can also use blue EHEIM coarse filter pads for the same purpose.
