FIX by EHEIM - 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 MECH or MECHpro by EHEIM . 

FIX by EHEIM 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.
