Filtration Systems: Nexus Eazy 200/300 How to Order    Shipping/Terms

Nexus 200 & 300 Eazy

The Nexus Eazy is Evolution Aqua's exciting new filter system.  It incorporates the industry proven Kaldnes Moving Bed technology coupled with the innovative Eazy mechanical filter.

Combined, they provide outstanding water clarity and quality, pump or gravity fed.  Extremely easy to clean and maintain, with minimal running costs, the Nexus Eazy system is designed and built to last a lifetime.

How the Eazy works - The Kaldnes is retained in a stainless steel basket and has been proven to trap incredibly small particles of waste. Cleaning the Kaldnes is a simple matter of turning on the air tap to the settlement area thus agitating it and causing the waste matter to be dislodged from the media so it can be drained to waste.

Nexus Eazy systems are complete units and include the Nexus body, Eazy central vortex, air backwash line, air diverter valve, unionized ball valves to waste, and Kaldnes media for both the Eazy (static Kaldnes) and the bio-reactor (fluidized Kaldnes).

The Nexus 200 Eazy and Nexus 300 Eazy are the same system in 2 sizes for different pond volumes.

  • Nexus 200 Eazy, 2640 gph max flow, for ponds up to 4700 gallons.
  • Nexus 300 Eazy, 3960 gph max flow, for ponds up to 8900 gallons.
