Sera Siporax 15MM Bio Filter Media

Advanced Bio Media for Crystal-Clear Aquatic Filtration

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.

Usage Instructions:

• Place media in filter compartment or sump using media bag/tray
• Rinse lightly before use
• No replacement needed under normal operation

Key Benefits:

• Enhanced biological filtration for crystal-clear water
• Reduces maintenance frequency and water change cycles
• Supports formation of effective biofilms and denitrification zones
• Long service life—does not break down over time
