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.

How the Nexus Works

Water from the pond enters the nexus via the inlet into the inner chamber which works as a vortex, allowing larger solids to settle out. Water then passes through the grills in the stainless steel “Eazy” filter, where the finer particles are removed by the static bed K1 Micro® filter media. The clean water then passes to the outside chamber of the Nexus for biological treatment before returning to the pond. At this stage, biological breakdown occurs through different strains of bacteria and filter feeders living on the protected surface area of each K1+ Media filer. The bacteria convert Ammonia and Nitrite into less harmful Nitrate. Water then passes through the exit grill into the outlet and returns to the pond.

Continuing our long standing reputation for innovation, the Nexus Automatic System now enables Nexus owners to benefit from a fully automated cleaning cycle

Physically turning ball valves and manually switching pumps on and off will now be a thing of the past thanks to the Nexus Automatic System. All of the key processes that form the cleaning cycle are now controlled automatically with this easy to install kit.
