Optimal Enhancement of Biological Filtration The innovative sera siporax Professional is designed for use in both freshwater and saltwater aquariums, as well as in ponds. Regardless of the type of filter (internal, external, or trickle filter), it maximizes the surface area essential for biological filtration and offers the perfect substrate for the establishment of beneficial filter bacteria. The filtration and decomposition processes occurring at the bottom of natural waters are crucial. Micro-organisms break down organic waste, making it available as nutrients for aquatic plants, while removing harmful substances such as ammonium, nitrite, and nitrate. In nature, the amount of waste produced per volume of water is minimal, meaning the existing bottom surface can support a sufficient population of micro-organisms. However, an aquarium represents a compact biotope within a limited space. Therefore, it is essential to maximize the settling area to ensure the thorough and safe decomposition of organic remnants. sera has successfully achieved this with the exceptional high-performance filter medium, sera siporax. In contrast to other filter rings on the market, sera siporax is made from sintered glass. This unique material features a special three-dimensional pore structure that significantly increases the surface area. Additionally, the fine pores create optimal conditions for the bacteria that degrade pollutants. As it forms an interconnected system, the bacteria are continuously flushed by water, enabling them to break down pollutants with maximum efficiency. Moreover, the distinctive pore arrangement allows for the self-cleaning of the substrate, resulting in very prolonged filter longevity. When paired with specialized bacteria, sera siporax also accomplishes various other specific functions, such as preventing algae growth and facilitating targeted water conditioning.
