EHEIM Fix 1 Litre

Prefilter material and fine filtration  as a separation layer between the mechanical and biological filter media This specially formed filter material is for use after the layer of EHEIM MECH or MECHpro. EHEIM FIX acts as a separation layer between the mechanical and biological filter media. This is where the larger dirt particles are trapped, thus removing them from the water before entry into the biologically functioning filter layers. To fit an EHEIM external filter, we also offer EHEIM coarse filter pads to achieve the same result.
