sera siporax Pond 25 mm (Supplied in a resealable plastic bag)
For crystal clear water in freshwater and marine aquariums as well as in ponds
sera siporax Professional is a highly effective, fully biological filter medium for achieving crystal clear water in aquariums or ponds. Suitable for all internal, external, trickle and pond filters.
The structure of sera siporax Professional is open pored, three dimensional and functional. This structure allows the formation of very effective biofilms that grow into the pores and coat their walls. The pores have the ideal size for ensuring long term water flow and supply of the bacteria. The biofilm also breaks down nitrate (denitrification) deep within the pore structure where oxygen levels are lower.
Not only nitrifying and denitrifying bacteria grow in the biofilm of sera siporax Professional, but also ones that break down organic matter. Dying bacteria therefore do not clog the pores but are broken down biologically. The biofilm grows and shrinks according to water pollution and thus adapts to the requirements. sera siporax Professional is therefore the only filter material that cleans itself biologically. The pore structure is perfect for being settled by bacteria.
Due to the special pore structure, sera siporax Professional develops its own ideal water current. It can therefore be used in filters with high and low flow rates, and in trickle filters.

What makes a good filter medium?
Whether in an aquarium or a pond: a high quality filter material is essential. Along with the filter, it ensures crystal clear water and unobjectionable water parameters. This is enough of a reason to consider the selected filter medium carefully. The important feature is not the price or the material surface, but the performance. Experienced aquarists or pond keepers therefore choose sera siporax Professional.
The filter medium performs one of the most important tasks for maintaining the biological equilibrium in an aquarium or pond: It ensures constantly good water quality. When buying a medium, fish lovers should therefore focus on the performance parameters.
Manufacturer statements detailing a large material surface do not necessarily indicate effective filtration. Those who choose their filter medium only considering the price are also thinking wrongly, because: Lacking performance leads to increased maintenance efforts which also affect the costs.
Clearly spoken: Ambitioned aquarium enthusiasts and pond lovers consider the quality of the filter material. sera siporax Professional provides an open pored and three-dimensional tunnel and pore structure. It allows the formation of particularly powerful biofilms that grow into the tunnels and pores, and cover their walls. Not only nitrifying and denitrifying bacteria multiply within the biofilms of siporax, but also those that break down organic matter. Dead bacteria therefore do not clog the pores. Until now, siporax is the only biologically self-cleaning filter medium. It ensures the supply of the bacteria due to its functional tunnel structure. It furthermore develops its own optimal water current, so usage in common, slow flux and trickle filters is no problem.
For comparison: Compared to ceramic filter materials, sera siporax Professional achieves 34 times as much breakdown performance. Simple filter media consisting of ceramic or clay tubes usually have a closed surface – and therefore no internal tunnel or pore structure. Bacteria can therefore settle only on the outside. Higher filter material requirements are the consequence.
The convincing price vs. performance ratio is also approved by the coral breeder “Korallenzucht Wendel” in Leinsweiler (Pfalz/Germany). The biofilters of the extensive breeding setup with live rock are equipped with 1,000 liters of siporax. It ensures optimal conditions for the difficult breeding of corals.
Due to its extraordinary properties, siporax can, however, also be found in the filter systems of many zoos. sera siporax Professional will be used in the filter system of the aquariums in the Darwineum, which is momentarily built, and which will demonstrate the evolution theory by Charles Darwin in the zoo of Rostock/Germany.
Conclusion: When buying, performance is very important for those who wish to provide their fish a healthy environment. The most important criterion is the structure or the qualities. It is worth investing in, even if the selected product is slightly more expensive.
