24 Less water changes with sera siporax Professional sera siporax Professional is placed in the filter and provides ideal working conditions for the dif- ferent purification bacteria from sera filter biostart. The break- down of pollutants starts immedi- ately. After mechanical prefiltration, food or plant leftovers as well as fish waste are converted into ammonium. On the large and rough surface mucous forming bacteria have best possible hold. They are sufficiently provided with oxygen. These bacteria convert ammonium into nitrite (aerobic process). The extremely high amount of open- pored tunnel structures in sera siporax Professional allows for ideal supply of the anaerobic bacteria with nutrients and small- est amounts of freshwater. There are oxy- gen-poor conditions within the tunnels, allowing for nitrite breakdown into nitrate. The bacteria are forced to break down nitrate as to get a sufficient oxygen supply. Therefore, nitrate is also continuously reduced. Remaining nitrate is consumed by aquatic plants as a nutrient. Due to the large internal cross section of the tubes, the breakdown products get re moved quickly, without permanently rinsing away the bacteria. Biological water cleaning Filter media for bacteria settlement should be tube-shaped. This allows the water to flow off inside them, and there is no clogging or sticking that could affect the filtration process. Important: Filtration according to natureTechnical equipment The surface of one liter (one US quart) of sera siporax Professional has almost as much biological breakdown power as 34 liters (9 US gal.) of clay filter material
