Evolution Aqua Nexus 220+

The New Nexus Plus Series

The Nexus 220+ 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.

The Nexus 220+ features an Eazy filter which utilises the K1 Micro in a static bed, to deliver improved levels of mechanical filtration. The Nexus filter systems also use the acclaimed K+ in the moving bed to deliver outstanding levels of biological filtration. Together these filter media deliver crystal clear and healthy water.

Key Features and Benefits

High Performance Mechanical Filtration

The design of the Eazy enables the Nexus to capture solids more effectively than before. K1 Micro is used inside the Eazy helping to capture fine particles, delivering unrivalled mechanical filtration.

Great Flow

The new Eazy features a 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 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 K+ 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.

Simple Solids Handling

Inside the centre mechanical stage of the Nexus, there is a large area for solid waste to be captured and to settle. This area can then be cleaned easily, ensuring the filter does not clog up with unnecessary amounts of waste.

Removable Eazy

All Eazy filters used in the Nexus+ 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 (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 K+ Media. This 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 K+ Media. These bacteria convert Ammonia and Nitrite into harmless Nitrate. The amount of Ammonia and Nitrite produced in the pond is dependant on feed rates and the type of food used. For higher feed rates additional K+ Media should be added into the outer chamber.

PLEASE NOTE: 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.
