Sera Siporax Professional[Volume - 50L]Maximum optimization of biological filtration The original sera siporax Professional is designed for both freshwater and saltwater aquariums, as well as ponds. Regardless of the type of filter used (internal, external, or trickle), it maximizes the surface area needed for biological filtration and offers the ideal substrate for beneficial filter bacteria to thrive. The filtering and decomposition processes found in natural water beds are crucial.
Maximum optimization of biological filtration The original sera siporax Professional is designed for both freshwater and saltwater aquariums, as well as ponds. Regardless of the type of filter used (internal, external, or trickle), it maximizes the surface area needed for biological filtration and offers the ideal substrate for beneficial filter bacteria to thrive. The filtering and decomposition processes found in natural water beds are crucial. Micro-organisms decompose organic waste, making it available as a nutrient for aquatic plants while eliminating harmful substances like ammonium, nitrite, and nitrate. In nature, the waste produced per amount of water is minimal, which means the existing bottom surface can support a sufficient number of micro-organisms. However, an aquarium represents a small ecosystem in a limited space. Therefore, it is essential to significantly enhance the settling area to ensure the thorough and secure breakdown of organic remnants. Sera has successfully achieved this with the innovative high-performance filter medium, sera siporax. Unlike conventional filter rings on the market, sera siporax is made from sintered glass. This distinctive material features a unique three-dimensional pore structure that maximizes surface area. Additionally, the fine pores create optimal conditions for bacteria that degrade pollutants. As it is an interconnected system, the bacteria are continually flushed by water, enabling them to eliminate pollutants with the highest efficiency. Moreover, the distinctive pore configuration allows for self-cleaning of the substrate, resulting in extended filter lifespan.Shipping Notes

Works perfect for BMW S63 engine.
I used this to change the oil on my BMW M8 with the S63 engine. It was a perfect fit. It extended far enough onto the filter housing to be quite secure with no risk of slipping off and stripping the housing. It was snug on the housing and did not bind up due to having a loose fit. The tool feels well-built and I suspect it will outlive me given my occasional personal use. It would still probably hold up well even for daily shop use as long as it was not abused (repeatedly dropped, slammed around, etc).
