The Nexus 320+
Evolution Aqua have launched the Nexus320+ and Nexus220+ filtration systems. Building on the tried and tested technology that has been ever present in the world renowned Nexus, the team at Evolution Aqua have gone even further to enhance their number one Koi pond filter.
The Nexus320+ and Nexus220+ 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 also supplied “auto ready”, with factory fitted fixings already in place, making it even easier to upgrade to the Nexus Automatic Cleaning System.
Easy To Clean And Maintain
A key feature of all Nexus 220+ and 320+ filtration systems is the sheer ease of maintenance. This still remains the case with the new Nexus systems. Simply operating a combination of air valves and waste valves ensures that the Eazy filter and main filter body can be easily cleaned to deliver consistent water quality.
Better Solids Handling
Inside the centre mechanical stage of the Nexus Eazy , there is a much larger area for solid waste to be captured and to settle.
This area can then be cleaned even easier than before ensuring the filter does not clog up with unnecessary amounts of waste.
Removable Eazy
All Eazy filters used in the Nexus Eazy 320+ and Nexus 220+ series can be removed if needed. This added feature is ideal when undertaking further maintenance.
How The Nexus+ Works
The Nexus+ filter is an innovative biological and mechanical filter system in one. 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. The water then passes through Eazy filter, where finer particles are removed at the mechanical stage of filtration, thanks to the static bed of K1 Micro filter media.
The mechanically clean water then passes to the outside chamber of the Nexus+ where the new K+ Media Moving Bed is located for biological treatment prior to being returned to the pond. At this stage, biological breakdown occurs through different strains of bacteria and filter feeders living on the vast protected surface area of each piece of the K+ Media. These bacteria convert Ammonia and Nitrite into less harmful Nitrate. Water then passes through the exit grill into the outlet, returning back to the pond.

Very helpful. Only negative – it was not explained that some of the equipment I ordered was coming directly from Evolution Aqua and not in the delivery from Cotswold Koi. This caused some confusion and arrived several days later than anticipated (actually with badly damaged packaging, although the contents turned out to be undamaged, but that was an issue for EA).
