EHEIM SUBSTRATEpro 3600g - high efficient biological filter media

After the first cleaning process by the mechanical filter media (e.g. EHEIM MECH or MECHpro) the biological filtration is the most important. It provides for clear, healthy water and stabile water values.

That's why there is invested a lot of time in research work into the development of biological filter media.

Tip:Never clean or change all the filter media together in one operation (and never clean too rigorously). The bacteria cultures must not be completely destroyed, otherwise recolonisation will be retarded. The filter baskets in the external filters and filter modules in the internal filters aquaball; biopower are ideal for partial cleaning.

Optimised bio-filter medium with perfect volume usage, long intervals between cleaning and top decomposition performance. SUBSTRATpro consists of pearl-shaped sintered glass. The spherical shape gives a high bulk density. Thus the whole of the volume in the filter (filter baskets or modules) can be utilised. Also the optimum surface of the beads provides intensive colonisation of the important purification bacteria. Due to the high number of bacteria, peak nitrite loads are more easily reduced and the maintenance intervals of the filter material are longer.
