Optimal Enhancement of Biological Filtration The original sera siporax Professional is ideal for use in both freshwater and saltwater aquariums, as well as in ponds. Regardless of the filter type (internal/external/trickle filter), it optimizes the surface area needed for biological purification and provides the perfect substrate for the establishment of essential filter bacteria. The processes of filtering and breaking down materials in the substrate of natural waters play a crucial role. Organic waste is decomposed by microorganisms, making it available as nutrients for aquatic plants, while harmful substances like ammonium, nitrite, and nitrate are eliminated. In nature, minimal waste is produced per unit of water, so the existing substrate surface is adequate to support a healthy population of microorganisms. On the other hand, an aquarium represents a compact ecosystem in a limited space. Therefore, it's essential to maximize the available settling area to ensure the thorough and safe decomposition of organic remnants. sera has successfully achieved this with the innovative high-performance filter medium, sera siporax. Unlike other filter rings found on the market, sera siporax is made from sintered glass. This distinctive material boasts a unique three-dimensional pore structure, facilitating a significant increase in surface area. Simultaneously, the fine pores create optimal conditions for bacteria that decompose pollutants. As it is an interconnected system, the bacteria are continually flushed with water, enabling them to break down pollutants with maximum efficiency. Moreover, the exceptional pore arrangement allows for self-cleaning of the substrate, resulting in very long filter lifespans.

Combining mechanical and biological filtration in a single system The filter cartridge can be easily replaced and showcased as a single unit. Simple to set up, straightforward maintenance, and high efficiency Ideal for both freshwater and saltwater tanks. This system offers both mechanical and biological filtration. Featuring a specialized carbon cartridge that purifies water, eliminates odors, and provides a habitat for beneficial bacteria. The Bio Cartridge boosts biological filtration and ensures optimal growth of nitrifying bacteria. It's user-friendly—just fill with water and plug it in. Maintenance is a breeze. Replace the carbon cartridge every two months for the best results.
