Evolution Aqua have launched the 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 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.
Faster filter maturation and unrivalled water clarity
Maximum pond size: 18,000 litres / 4,000 gallons
Recommended flow rate: 6,000 litres per hour
Maximum flow rate: 10,000 litres per hour
Volume of water in Nexus: 510 litres
Amount of K1 Micro in EAZY: 18 litres
Amount of K+Media supplied: 50 litres
Maximum amount of K+Media: 150 litres
How the Nexus+ Works
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.
Nexus+ Dimensions
Installing the Nexus+
The Nexus+ MUST be installed on a solid, level base, a minimum of 1.2 metres x 1 metre. Failure to do this will cause irreparable damage to the filter and will therefore invalidate your warranty.
GRAVITY-FED INSTALLATIONS
By this we mean that your pump is going to be used to return the filtered water to the pond and therefore your filter will be supplied by gravity via a larger diameter pipe. In this situation the water level in the filter will be at the same level as the pond.
PUMP-FED INSTALLATIONS
By this we mean that if your pump is going to be used to supply the water to the filter, and the filtered water then returns back into your pond via gravity, i.e. down a waterfall, or through a large diameter pipe, this is referred to as PUMP FED (i.e. the water is fed to the filter using a pump).
