Evolution Aqua Nexus Easy 320 Filter

Nexus 220 and 320

Introducing the next generation of Nexus Filtration Systems from Evolution Aqua.

The Nexus 320 and Nexus 220 filtration systems deliver 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, whilst being incredibly easy to clean and simple to install.

The Nexus 220 and 320 feature a re-designed Eazy filter which now 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 this combination of filter media work to deliver crystal clear and healthy water.

All Nexus filtration systems can be installed on pump fed or gravity fed setups depending on your pond configuration. The Nexus 220 is suitable for ponds up to 18,000 litres (4,000 gallons) while for larger ponds the Nexus 320 can be installed on ponds up to 34,000 litres (7,500 gallons).

Key Features and Benefits

Improved Mechanical Filtration The new design of the Eazy enables the Nexus to capture solids more effectively than before. 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 the Eazy through all sides and from below, much more effectively than before. This feature combined with the use of K1 Micro makes for improved flow rates through the entire mechanical filter stage.

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 220 and 320 systems. The Eazy is simply cleaned by using a combination of the cleaning pipe, air valves and ball valves fitted to the Nexus, meaning you don’t need to get your hands dirty. The clear lid fitted to the Eazy also makes it easy to visual inspect the K1 Micro media.

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 with the K1 Micro in place. This added feature is ideal when undertaking further maintenance.

How The Nexus WorksThe Nexus filter is simple yet innovative. Water enters the Nexus via the inlet into the inner chamber which works as a basic vortex allowing larger solids to settle out. The water then passes through the Eazy where the finer particles are removed at the mechanical stage of filtration. From the Eazy the water passes into the outer chamber where the biological stage of filtration takes place. An air pump is used to constantly aerate the K1 Media in the outer chamber ensuring the moving bed delivers fantastic results.

Water then passes through the grill into the Exit Chamber, where it is returned to the pond through the outlet.

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.

Biological Filtration The outer chamber of the Nexus contains the moving bed of K1 Media. 100 litres of K1 Media is supplied with the Nexus 320 with the option to add an extra 200 litres of K1 Media should it be needed. The Nexus 220 is supplied with 50 litres of K1 Media, with the option to add an extra 100 litres of K1 Media if needed. This allows your filter’s biological capability to grow with your fish.

The outer chamber is where the final stage of biological treatment occurs. Biological breakdown occurs through different strains of bacteria living on the protected surface area on each piece of the K1 Media. These bacteria convert Ammonia and Nitrite into harmless Nitrate. The amount of Ammonia and Nitrite produced in the pond is dependent on feed rates and the type of food used. For higher feed rates additional K1 Media should be added into the outer chamber.
