sera siporax pond is a fully biological filter material for almost all garden pond filters 1 liter (1 US quart) sera siporax pond provides as much settling area for bacteria as, approximately 34 liters (9 US gal.) of clay filter material. Prefilter with sera biofibres coarse to prevent large particles from entering the biofilter. sera siporax pond provides bacteria an extremely large amount of open-pored tunnel structures. This allows an ideal supply of the bacteria with nutrients and a smallest amount of fresh water. There are oxygen-poor conditions within the tunnels. This makes the bacteria crack nitrate to get enough oxygen. Consequently, they continuously break down nitrate, and the pond water remains low in nitrate. 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. Calculation formula for sera siporax pond: One single liter (one US quart) sera siporax pond is sufficient for purification of 1,000 liters (264 US gal.) pond water with 20 pond fish of 10 cm (4 in.) length each or a comparable stock ［representing approx. 1.5 kg (3.3 lb.) of fish fed with up to 40 g (1.4 oz.) high quality food per day] and release it from organic pollutions in long terms.

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 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. 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 nd so can break down pollutants with best possible efficiency. Furthermore, the unique pore array allows for self-purification of the substrate and thus very long filter holding times.

FEATURE This product consists of the diving pump and biochemical filter. The pump body is made from diecast ABS engineering plastic and can endure shock and rust. Made of stainless steel, the pump shaft can be used in freshwater and seawater. The motor is sealed in the body with resin. With good waterproof performance and high isolation intensity, with the protector for heat, it is safe and reliable. Multifunctional design, various purposes in a machine-pumping, adding oxygen, filtering and UV sterilizing4in 1 (SP-B SP-C series do not include UV light).
