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 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.

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).

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.

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.

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.

Pre-filter to remove waste & debris

The Cetus sieve is a bow screen pre-filter, made using the latest rotational molding technology. With all of its benefits and build quality, it is undoubtedly the best of its kind on the market today, regarding quality and performance! It is designed to efficiently and effectively remove large amounts of mechanical waste from a pond. It can be set-up gravity OR pump fed and has many benefits over the original bow screen technology.

Cetus Sieve

Overview

The Cetus Sieve is a self-adjusting sieve which can be installed either gravity fed or pump fed. The Cetus Sieve enables your pond water to be filtered of large amounts of waste and debris before the water enters your current filter system. This process is commonly referred to as “pre-filtering”. The Cetus Sieve can also be used as a stand-alone unit to remove leaves and other floating debris from your pond via a surface skimmer. The Cetus Sieve will efficiently and effectively remove large amounts of mechanical waste from your pond. The Cetus Sieve is compatible with all filtration systems, however it is the perfect prefilter for the Evolution Aqua Nexus filter range. For gravity fed systems the Cetus Sieve has a weir which will automatically adjust to the flow rate of your pump. (Max flow rate 18,000 litres/hr) When the Cetus Sieve is used in front of any other biological/mechanical filter the period in between cleaning will be extended. The biological process is improved by the removal of organic matter which would consume oxygen and leach ammonia and other compounds into the water.

How the Cetus Sieve works

Installing the Cetus Sieve The Cetus Sieve has a variable inlet height using the unique patented Pondflow regulation system – for use when gravity fed. This allows water levels within the pond to drop without causing the circulating pump to be starved of water. The Cetus will allow a skimmer or a bottom drain to accept vast amounts of waste without excessive cleaning needed to be carried out. The water must then be pumped to either a normal filter above pond level (Nexus Eazy/Eazy Pod) or to a pressurised filter.

If pump fed, the sieve is placed above pond water level and then the exit water is gravity dropped into your main filter.

The Cetus sieve is a bow screen pre-filter, suitable for pre-filtration of any biological filter including all pressured filters. It is advised that all pressurised filters be pre-filtered using a Cetus to reduce excessive backwashing and maintenance due to heavy solids.

How the EazyPod Automatic works

The concept of the EazyPod Automatic is simple and yet innovative. Water enters via the inlet and
passes over an 18 watt UV Clarifying bulb (on UV versions ONLY), helping to kill any single celled algae
in the water.

The water then enters the outer chamber, which runs around the entire circumference of the
EazyPod. Between the outer chamber and the inner chamber, there is a stainless steel perforated
screen. These perforations are situated in the lower half of the screen and around its entire face.
This means that when the water passes from the outer to inner chamber,
a downward and upward flow is created. This causes many of the larger solids to settle in the base
of the outer chamber, due to the force of gravity.

The size of the perforations will not allow large mechanical waste to enter the inner chamber,
thus acting as a first stage mechanical filter. The inner chamber holds 18 litres of static K1 Micro
media. As the water enters the inner chamber, the fine smaller solids become entrapped in the K1
Micro. After passing through the K1 Micro, the clean water then rises and overflows into the inner
return pipe. From here it returns to the pond via the return outlet.

The EazyPod Automatic filtration system gives water quality and clarity that surpasses all
expectations. The nature and volume of the K1 Micro means, that when static, apart from being
a very efficient mechanical filter, there is more than enough surface area for beneficial bacteria to
colonise. Therefore on a smaller pond, the EazyPod Automatic is an excellent complete filter.

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).

Cleaning Cycle

The K1 Micro is cleaned by the integrated air pump located inside the control box, that is connected to the air line in the EazyPod Automatic, which in turn goes to an air ring in the base of the inner chamber. The air ring has small holes in it which causes the K1 Micro to move and therefore clean itself.
During the cleaning cycle, the finer particles escape into chamber from the K1 Micro. This waste water will be automatically dumped via a 1½ inch motorised ball valve.

Cleaning is fully automated on the EazyPod Automatic, and is controlled by a built-in timer, which is factory set at one clean every 3 days, however, this is easily adjustable to fit in with your pond requirements. The EazyPod Automatic will run a cleaning cycle which lasts approximately 6 and a half minutes.

How the EazyPod Complete works

Water from the pond enters the EazyPod Complete via the inlet, cascading around the 18 Watt UV-C bulb, where any algae will be exposed to the UV-C radiation.

The water then flows around the circumference of the outer chamber of the EazyPod Complete, passing through the stainless steel grill causing many of the larger solids to be filtered out and settle in the base of the outer chamber. This is the first stage of mechanical filtration.

As water enters the central chamber, through the stainless steel grill, the fine smaller solids become trapped in the mass of K1 Micro. Bio-films build up on the protected surface area within each piece of media, allowing biological filtration to take place.

After passing through the K1 Micro, the clean water then rises and overflows into the inner return pipe and flows back to the pond via the outlet.

The EazyPod Complete is incredibly simple to clean. The connected air pump is used during the cleaning cycle to agitate the K1 Micro to free up any debris and waste that has built up within the filter.

All EazyPod Complete models are supplied with a 70 litre per minute air pump and accessory kit.
