Product Description
The innovative Nexus Automatic System enables Nexus Filter owners to benefit from a fully automated cleaning cycle on their multi award winning Nexus filtration systems. Available in 3 different models to suit Nexus Pump Fed set ups as well as Nexus 220 and Nexus 320 Gravity Fed installations.
Physically turning ball valves and manually switching pumps on and off will become 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.
The Nexus Automatic System is factory set to perform the cleaning process every 3 days, but the frequency of cleaning can be altered from once an hour too once every 10 days depending on the cleaning frequency which suits you and your pond. The cleaning cycle can also be performed manually, by triggering the manual clean button on the control box.
Nexus Automatic System - 220 Gravity Fed Main Components:
The Evolution Aqua Nexus 320+ provides an advanced filtration system for Koi ponds. 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 Nexus 320+ filters now come supplied with the new K+ Advanced Floating Filter 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.
How The Nexus+ Filter 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 the 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+ Advanced Filter 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+ Advanced Filter 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.
New K+ Advanced Floating Filter Media Plastic media, for use in biological pond filters - specifically in moving bed bio reactors, was pioneered by Evolution Aqua, some 20 years ago. In recent years, other plastic media have come onto the market, usually with the aim of trying to get more and more surface area. However, one drawback to using plastic media has always been the time it takes to establish a stable biofilm – essential for good filtration. After many years of research, Evolution Aqua have now developed a new media that not only gives class leading surface area, but also overcomes the problem of long maturation times.
K+ Media is designed and manufactured in the UK by Evolution Aqua. This advanced media, with its innovative design, and class leading surface area provides enhanced biological and mechanical filtration. As Evolution Aqua extrude K+ Media, Minerals and Enzymes are added to the raw material. The result of this process, unique to Evolution Aqua, is a filtration media that not only outperforms most of its competitors due to its large protected surface area, but also answers the problem of how to speed up the time taken to mature your filter.
Increased Surface Area With a new shape and profile, K+ Media has also been designed to have an increased and class leading surface area, meaning an overall surface area of 1,350m2 per m3. More importantly for biological filtration, the protected surface area of K+ Media is 1,025m2 per m3. This allows a stable bio-film to form and remain intact when used in moving bed biological filtration, as in the new Nexus+.
