Sera siporax Professional is a high-performance filter medium suitable for freshwater and marine aquariums and ponds. It maximizes the surface area required for biological purification and provides optimal conditions for filter bacteria to settle. The sintered glass material with a three-dimensional pore structure increases the surface area, ideal for bacteria to break down pollutants. It allows for self-purification of the substrate, resulting in long filter holding times. The unique interconnected system ensures maximum efficiency in breaking down pollutants.
