sera siporax Professional is the highly effective fully biological filter medium for all internal, external and trickle filters in freshwater and marine aquariums as well as for pond filters. The structure of sera siporax Professional is open pored, three di- mensional and functional. This structure allows the formation of very powerful biofilms that grow into the pores and cover their walls. The pores provide the ideal size for ensuring water currents and bacteria being supplied in the long run. The biofilm even breaks down nitrate (denitrification) in the deep zones of the pore structure where oxygen levels are lower. Not only nitrifying and denitrifying bacteria grow within the biofilm of sera siporax Professional, but also those that break down organic matter. Dying bacteria therefore do not clog the pores but are bro- ken down biologically. The biofilm grows and shrinks according to water pollution, and so adapts to the requirements. sera siporax Professional is therefore the only filter material that cleans itself biologically. Due to the special pore structure, sera siporax Professional devel- ops its own ideal water current. This allows using it in fast flow, slow flow and trickle filters. sera filter biostart sera filter biostart immedi- ately accelerates the biologi- cal filter performance. Sludge and unpleasant odors will no longer occur. The enzymes break down organic material (uneaten food, fish waste) into smaller fragments. These are then broken down further by the highly active micro orga- nisms in the filter. sera siporax mini Professional 130 g (4.5 oz.) 270 g (9.5 oz.) sera siporax Professional 500 ml (145 g/5.1 oz.), 1,000 ml (290 g/10.2 oz.), 10 l (2.9 kg/6.4 lb.), 50 l (14.5 kg/32 lb.) sera siporax – for crystal clear water in freshwater and marine aquariums as well as in pond filters Pore structure on the surface Pore structure on the inside Inner surface settled by bacteria films Three dimensional tunnel structure sera siporax NO- 3 NO- 2 NH+ 4 NH3 14 Aquarienbroschüre US.indd 14 06.11.2012 13:15:52
