Evolution Aqua's Nexus is the world leading filtration system incorporating the industry proven Kaldnes Moving Bed™ coupled with the exceptional Eazy mechanical filter. It's high efficiency and adaptability can handle koi ponds up to 9,000 gallons with a single unit. As more fish are added, or grow, more media is added to handle the load.
The media chamber never needs maintenance, and cleaning the Eazy is a matter of turning on the air bubbling in the static media area to dislodge all debris in minutes. Only 30 gallons of water are used do dump the Eazy. The whole process is simple and can be done without even getting wet.
