Sera Siporax 15MM Bio Filter Media delivers professional-grade biological filtration for freshwater, marine, and pond setups. Developed in Germany by Schott AG, each ring features an open-pore, 3D design that maximizes biofilm growth while maintaining water flow for long-term performance.
The media fosters aerobic and anaerobic bacteria—including nitrate-consuming colonies deep within the structure—making it ideal for ammonia, nitrite, and nitrate reduction. Sera Siporax is laboratory-tested for nitrate breakdown and offers far superior surface area versus standard ceramic media.
