EHEIM SUBSTRATpro 180g ≈ 250ml filter media

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 fresh and marine water, is washable and can be reused.Optimised bio-filter medium made from sintered glassHigh bulk density due to spherical shape (beads)Very dense colonisation of bacteriaLonger intervals between cleaningBetter reduction of nitrite loadsReusable (rinse carefully to clean)Suitable for fresh and marine waterThe main task of biological filter media is to offer the best colonisation conditions for the bacteria cultures, so that after a short time a bacteria lawn develops. The bacteria feed on dirt particles of all kind and convert substances critical for the aquarium.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 we have invested a lot of 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 and biopower are ideal for partial cleaning.Optimised bio-filter medium with perfect volume usage, long intervals between cleaning and top decomposition performance.mechanically:NoBiological:YesAbsorptive:NoChemical:NoNet bag:NoFreshwater:YesSea water:YesWidth:60 mmHeight:141 mmDepth:59 mm SUBSTRATpro consists of pearl-shaped sintered glass.
