Maximum optimization of biological filtration

The original sera siporax Professional is suitable for use in both freshwater and marine aquariums as well as in ponds. Not depending on the kind of filter (internal/external/trickle filter), 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 is processed by micro-organisms and is 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. It is, therefore, necessary to maximally enlarge the settling area for ensuring complete and safe breakdown of organic remainders.
sera perfectly put this into practice with the unique high-performance filter medium sera siporax.

Unlike other filter rings available on the market, sera siporax consists of sintered glass. The unique material convinces due to a special three-dimensional pore structure. This allows maximum surface increase. At the same time, the fine pores provide ideal settling conditions for bacteria that break down pollutants. Since it is an interconnected system, the bacteria are permanently rinsed by water and so can break down pollutants with the best possible efficiency. Furthermore, the unique pore array allows for self-purification of the substrate and thus very long filter holding times.
