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.
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
Maximum pond size: 34,000 litres / 7,500 gallons Recommended flow rate:11,000 litres per hour Maximum flow rate:13,000 litres per hour Volume of water in Nexus:840 litres Amount of K1 Micro in EAZY:20 litres Amount of K+Media supplied:100 litres Maximum amount of K+Media:300 litres
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.
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).
