• 500m2 per m3 protected surface area
• Dramatically increases the efficiency of filter systems
• Provides a large surface area for bacteria to colonise
• Provides mechanical and biological filtration
• Use in static and moving bed filter systems

Moving bed media has many advantages over traditional static bed filters, including a huge surface area which is always exposed to maximum oxygen and food for the bacteria, self-cleaning media as it tumbles, and the world famous protected surface area, enabling bacteria and higher organisms to dwell in their preferred location inside the media, exposed to oxygen and food, but safe from harmful cleaning practices.
