The Nexus 220+

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.

K+ Advanced Filter Media
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 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.
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+.

Easy To Clean And Maintain

A key feature of all Nexus 220+ and 320+ 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 Eazy , 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 Eazy 320+ and Nexus 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.

  • 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

Nexus Automatic System

Continuing our long standing reputation for innovation, the Nexus Automatic System now enables Nexus owners to benefit from a fully automated cleaning cycle on their multi award winning Nexus filtration systems. Physically turning ball valves and manually switching pumps on and off will now be 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.

Overview

The Nexus Automatic System can be installed on Nexus 220 and 320 filters manufactured after 2006, whether on gravity-fed or pump-fed installations. The kit includes a control box which connects up to an automated
waste valve, airpump control box and an automatic inlet slide plate (for gravity fed models only). Once installed and connected to your pond pump and mains power the system will carry out cleaning cycles at timed intervals or when pressing the manual clean button.

Cleaning Cycle

The Nexus Automatic System will control the cleaning cycle fully automatically. Cleaning is done on a timer, which is factory set to clean once every 3 days, however, this is easily adjustable to fit in with your pond requirements. The Nexus Automatic System will run a cleaning cycle which lasts approximately 10 minutes.

 

Gravity Fed Cleaning Cycle

■ Adjustable timer kicks in to start a cleaning cycle.

■ Control box automatically switches circulating pump off.

■ The water level in the Nexus equalises.

■ Inlet valve closes whilst at the same time air is diverted from the outer bio chamber to the EAZY to clean the media.

■ After the media has been cleaned, the waste valve opens.

■ EAZY is drained to waste and inlet valve opens for a final flush of the EAZY.

■ The waste valve closes.

■ Air is diverted back from the EAZY to the bio chamber.

■ Circulating pump is switched back on.

■ Nexus returns to filtration mode.

 

Pump Fed Cleaning Cycle

■ Adjustable timer kicks in to start a cleaning cycle.

■ Control box automatically switches circulating pump off.

■ The water level in the Nexus equalises

■ Air is diverted from the outer bio-chamber to the Eazy to clean the media.

■ After the media inside the Eazy has been cleaned, the automated waste valve opens.

■ Eazy is drained to waste.

■ The automated waste valve closes.

■ Air is diverted back from the Eazy to the biochamber.

■ Circulating pump is switched back on.

■ Nexus returns to filtration mode.removed if needed with the K1 Micro in place. This added feature is ideal when undertaking further maintenance.

 

The generally accepted practice is that when you keep ornamental fish, whether in a pond or in an aquarium, to keep the water fresh, 10% of the volume of the water in the pond/aquarium should be changed on a weekly basis. With this in mind, we recommend that you set your Nexus Automatic system to run a cleaning cycle so as to exchange water in line with this.general parameters of our ponds is turn over rate. This is the time that it takes for the total volume of the pond to pass through the filter system once. We recommend that for ideal performance a turn over rate of every 2 to 3 hours is found to be best.

Evolution Aqua Tempest Filter

Evolution Aqua Tempest Filter

The Tempest Filter is an innovative polishing system for ponds that will help to deliver crystal clear, healthy water. Designed to be used in conjunction with most filtration systems, the Tempest offers additional mechanical and biological filtration. The Evolution Aqua Tempest Filter can also be used on quarantine systems or as a standalone filter on smaller ponds.

The Evolution Aqua Tempest Pond Filter is easy to install and is simple and quick to clean, by way of a unique, patent pending air syphon design. During the cleaning process, air is drawn into the filter as it empties which causes the water to agitate, effectively cleaning the K+Media.

Using Evolution Aqua’s K+Media as the filter media, particles down to one micron can be filtered. Not only that, K+Media is the result of extensive research and development, moulded with minerals for faster maturation times.

E A Tempest Filters can be installed on a variety of set-ups. On larger systems that require a higher flow rate, multiple Tempest Filters can be installed in a modular system.
