Eheim Substrat Pro Bio-Filter Medium, 250 ml

• Optimised bio-filter medium made from sintered glass
• High bulk density due to spherical shape (beads)
• Better reduction of nitrite loads

Product Description 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. Eheim Product Number 2510021 Directions Place the filter medium in the filter of your aquarium. The filter medium does not need to be dosed like a liquid treatment. Instead, it should be left in the filter to allow the colonization of cleaning bacteria. Clean the filter media when the filter performance decreases. The filter medium is washable and can be reused. Box Contains SUBSTRAT PRO 250ML
