EHEIM Substrat Pro 250mL - 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.
Aquarium Kingdom Tips
When cleaning your filter always use water from the aquarium, not tap water. 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 re-colonisation will be disrupted.
