sera siporax mini Professional was developed especially for smaller aquariums up to a volume of approximately 100 liters. It allows maximum increase of the settling surface for purification bacteria but has a compact shape at the same time. This allows biological filtration even when using smaller filter units. The water parameters stabilize lastingly, the maintenance effort is reduced.
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.
