Maximize Biological Filtration Efficiency The original sera siporax Professional is designed for both freshwater and saltwater aquariums, as well as ponds. Regardless of the filter type (internal, external, or trickle), it optimizes the surface area necessary for biological filtration and provides an ideal substrate for the establishment of essential filter bacteria. The filtration and decomposition processes that occur at the bottom of natural bodies of water are crucial. Micro-organisms process organic waste, making it accessible as nutrients for aquatic plants, while effectively removing pollutants like ammonium, nitrite, and nitrate. In nature, minimal waste is generated per volume of water, allowing for sufficient micro-organism populations on the existing substrate. However, an aquarium is a compact ecosystem, making it essential to maximize the settling area to ensure complete and safe breakdown of organic residues. sera has achieved this with their innovative high-performance filter medium, sera siporax. Unlike other filter rings on the market, sera siporax is made from sintered glass. This unique material features a distinctive three-dimensional pore structure that significantly increases the surface area. Additionally, the fine pores create the perfect conditions for bacteria to thrive and decompose pollutants. Since it operates as an interconnected system, the bacteria are continuously flushed by water, enabling them to break down contaminants with optimal efficiency. Moreover, the exceptional pore configuration facilitates self-cleaning of the substrate, resulting in extended filter lifespan.

Maximum enhancement of biological filtration is achieved with the original sera siporax Professional, which is designed for use in both freshwater and marine aquariums, as well as in ponds. Regardless of the filter type—be it internal, external, or trickle filter—this product optimizes the surface area necessary for biological purification and offers the ideal substrate for beneficial filter bacteria to thrive. The filtration and breakdown processes that occur in the substrate of natural water bodies are crucial. Micro-organisms process organic waste, making it available as a nutrient for aquatic plants while eliminating pollutants like ammonium, nitrite, and nitrate. In nature, minimal waste is produced relative to the water volume, allowing the existing substrate to adequately support a healthy population of micro-organisms. However, an aquarium represents a small ecosystem in a confined space. Therefore, it is essential to maximize the settling area to ensure the thorough and effective breakdown of organic residues. sera has masterfully accomplished 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 specialized three-dimensional pore structure, which significantly enhances the surface area. Simultaneously, the fine pores create optimal conditions for bacteria that detoxify pollutants. Being an interconnected system, the bacteria are continuously washed by water, enabling them to decompose pollutants with maximum efficiency. Additionally, the unique pore configuration promotes self-cleaning of the substrate, resulting in extended filter longevity.

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.

Introducing a high-performance filter medium designed specifically for smaller aquariums, sera siporax mini Professional is ideal for tanks with a capacity of up to approximately 100 liters. This innovative product maximizes the settling surface available for beneficial purification bacteria while maintaining a compact shape, making it suitable for use with smaller filter units. As a result, water parameters stabilize over time, and maintenance efforts are significantly reduced. The processes of filtering and breaking down waste in the substrate of natural water bodies play a crucial role in maintaining a healthy ecosystem. Micro-organisms break down organic waste, turning it into nutrients for aquatic plants while effectively removing harmful substances like ammonium, nitrite, and nitrate. In nature, minimal waste is produced relative to the volume of water, ensuring that the existing bottom surface can support a sufficient population of micro-organisms. However, an aquarium represents a small biotope in a confined space, necessitating an increase in the settling area to guarantee the complete and safe breakdown of organic remnants. Sera has expertly achieved this with the exceptional filter medium, sera siporax. Unlike conventional filter rings found on the market, sera siporax is crafted from sintered glass, which boasts a unique three-dimensional pore structure. This innovative material enables a maximum increase in surface area, while the fine pores create optimal conditions for the bacteria that break down pollutants. The interconnected system allows for continuous water flow, ensuring that the bacteria are consistently rinsed and can efficiently degrade contaminants. Moreover, the distinctive pore arrangement facilitates self-cleaning of the substrate, resulting in extended filter longevity.
