Advanced filtration systems for Koi ponds now with NEW K+ Media
Building on the tried and tested technology that has been present in the world renowned Nexus, the team at Evolution Aqua have gone even further to enhance their number one koi pond filter.
The Nexus 220+ and Nexus 320+ filters now come with a new filter media called K+ Media in the moving bed outer chamber for vastly improved biological filtration and faster filter maturation. The new Nexus+ filters are now supplied "auto ready", with factory fitted fixings already in place, making it even easier to upgrade to the Nexus Automatic Cleaning System.
