SUBSTRATEpro 1440g - high efficient biological filter media

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. EHEIM SUBSTRATpro is suitable for fr esh and marine water is washable and can be reused.
