Evolution Aqua – K1 Micro Media

Evolution Aqua revolutionised the Koi market when it brought ground breaking moving bed filtration technology to a koi filter, with Nexus.

• 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

K1 Moving Bed Technology

Moving bed media has many advangates 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.

Over the last twenty years there has been a wholesale shift over to moving bed technology in pond filters, and Evolution Aqua were the pioneers. No one has much experience or has carried out as much research and development into this important area of biological filtration as Evolution Aqua. Nexus and Eazy Pod use K1 and K1 Micro filter media exclusively, and the filters and filter media are all designed and manufactured in the UK.
