The 2024 Nexus + Plus Advanced Filtertion Systems 220 & 320 Models
Advanced filtration systems for Koi ponds now with NEW K+Media
{Description}
Evolution Aqua have recently launched the Nexus 320+ and Nexus 220+ Plus 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 Nexus 220+ and Nexus 320+ 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 optional Nexus Automatic Cleaning System
{Features}
Features:
Latest K+ media for biological filtration
Faster filter maturation
Minerals added to media
Class leading surface area
Stable bio-film production
Easy auto cleaning kit upgrade
{How it works}
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 stainless steel grills in 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+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
{Installing the Nexus}
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)

Air Pump Requirements:
You can increase the biological capacity of your Nexus+ by adding additional K+ Media into the outer chamber up to teh maximum capacity
You will however need to ensure that you have the correct size of air pump (not supplied) to enable the K+ Media to move sufficiently

50 - 75 Litres / EA Air Pump 75
75 - 100 Litres / EA Air Pump 95

{Optional self cleaning add on}
Nexus + Automatic Self Cleaning Add On
The Nexus+ Automatic Cleaning 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 Cleaning System is factory set to perform a 10 minute cleaning process every 3 days, but the frequency of cleaning can be altered from once an hour to 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
The Nexus+ Automatic Cleaning System is supplied with the following components (Pump fed versions do not have the automatic inlet plate)
Automatic Inlet Plate
Automatic Waste Valve
Control Box
Air Control Valve Box
Hassle-free way to clean Nexus filtration systems
Automates the cleaning process of the Nexus
Easily fits onto Nexus filters (post-2006 models)
Electronic control box automatically operates valves and pumps
Adjustable timer controls the frequency of the cycle
Easy to set up for multiple cleaning cycles
Manual cycle can be carried out at the touch of a button
Gravity fed and pump fed versions available
{Media used in this filter}
Media used in this filter:
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
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+
Stable bio-film development. The 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
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
