Nexus Eazy 320 + Ref: NEXEAZY320+ Introducing the next generation of Nexus Filtration Systems from Evolution Aqua. The Nexus 320 filtration system delivers dramatically improved levels of clarity for ponds. Building on the success of the award winning Nexus range this new generation of filters cleverly combine mechanical and biological filtration into one advanced filter system. The Nexus 320 feature a re-designed Eazy filter which utilises the all new K1 Micro Filter Media, in a static bed, to deliver improved levels of mechanical filtration. The Nexus filter systems also use the acclaimed K1 Media in the moving bed to deliver outstanding levels of biological filtration. Together these filter media deliver crystal clear and healthy water.

K1 Micro is used inside the re-designed Eazy helping to deliver improved capture of fine particles, delivering unrivalled mechanical filtration. Improved Flow The new Eazy features an improved pattern of slots in the stainless steel body which makes the filter more efficient. Water can pass through all parts of the Eazy much more effectively. This feature combined with the use of K1 Micro makes for improved flow rates through the entire mechanical filter. Dramatically Improved Clarity The Nexus 320 and 220 filter systems use two types of filter media to deliver optimum levels of clarity in your pond. K1 Micro is used in the Eazy to improve mechanical filtration while the tried and tested K1 Media is used in the moving bed outer chamber, delivering the biological filtration. Easy To Clean And Maintain A key feature of all Nexus 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, 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 320 / 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. The Eazy Filter The Eazy is a stainless steel vessel containing a set volume of K1 Micro Media (20 litres in the Nexus 320 and 18 litres in the Nexus 220) which is located within the inner chamber of the Nexus. After water enters the Nexus it rotates around the Eazy in the inner chamber with a downward motion allowing the larger solids to settle to the bottom of the chamber before passing through the slots of the Eazy into the static K1 Micro. The water flows from all angles through the K1 Micro where improved mechanical filtration and settlement takes place and fine particles are caught within the K1 Micro. The water then flows through the slots in the centre column and into the outer chamber.

New advanced filtration 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. Minerals added for faster filter maturation During the extrusion process, Evolution Aqua add a range of minerals, along with magnesium, calcium, enzymes and salt to the raw material that is used to manufacture K+Media. The result means that K+Media will mature much faster than many other types of media. - The addition of these minerals creates a rough surface on the media. This textured surface has a microscopic honeycomb of peaks and craters that allow waste particles to collect, and nitrifying bacteria to form. - The minerals act as a food source for the bacteria, helping the bacteria to develop and multiply at a faster rate, further improving maturation times. - Calcium alone has proven advantages for developing and maintaining effective bio-films. - The enzymes that are added also help to make the media sticky so waste particles can adhere to media easier. - Salt is added during the extrusion process, which is dissolved during the cooling process, leaving a rough surface on which bio-film can easily adhere. 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+. To ensure excellent biological filtration of a Nexus maintain a pond pH of 7 or higher. Bacteria conversion rates are reduced in cooler temperatures. Stable bio-film development e shape of K+Media optimises the amount of quiet zones within the media where a stable bio-film can develop. Whilst K+Media keeps the integral profile of K1 Media at its core, there is an extra layer of cells and fins around the outside of each piece that enable microscopic organisms such as Rotifers and Vorticella to thrive. This is an additional benefit as competitor media do not have such quiet zones that would allow these higher lifeforms of filter feeders to develop. The bacteria and organisms that form within the bio-film ensure the media delivers optimum levels of biological filtration in the moving bed, which has been proven filtration technology for many years in the fishkeeping hobby.
