Sera siporax Professional for use in both freshwater and marine aquariums as well as in ponds. It maximizes the surface required for biological purification and provides the optimal substrate for the settling of necessary filter bacteria. Filter and breakdown processes in the bottom ground of natural waters are very important. Organic waste are processed by micro-organisms and are thus available for the natural cycle as a nutrient for aquatic plants – pollutants such as ammonium, nitrite and nitrate are removed. Since little waste per water amount is formed in nature, the present bottom surface is sufficient for housing a sufficient number of micro-organisms. However, an aquarium accommodates a small biotope in little space. Sera perfectly put this into practice with the unique high performance filter medium Sera siporax. Sera siporax consists of sintered glass with a special three-dimensional pore structure for maximum surface increase. At the same time, the fine pores provide ideal settling conditions for bacteria that break down pollutants.
