INTRODUCING THE NEXUS 220
2
Congratulations on purchasing an Evolution Aqua Nexus 220 filtration system.
The Nexus 320 and Nexus 220 filtration systems deliver dramatically improved
levels of clarity for Koi ponds. Building on the success of the award winning Nexus
range this new generation of filters feature a re-designed Eazy filter which utilises
K1 Micro Filter Media to deliver improved mechanical filtration. The Nexus filter
systems also use K1 Media in the moving bed to deliver consistent biological
filtration, ultimately providing healthy water and better clarity. There’s also
improved flow in all directions through the Eazy and a better settlement of solids.
Please read this instruction manual carefully from start to finish before attempting
to install your new Nexus 220.
