Evolution Aqua Nexus 320 Pond Filtration Systems 9000 Gal. NEXEAZ320 -

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.

Overview

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).

How the Nexus Works

Water from the pond enters the nexus via the inlet into the inner chamber hich works as a vortex allowing larger solids to settle out. Water then passes through the grills in the stainless steel “Eazy” filter, where the finer particles are removed at the mechanical stage of filtration, thanks to the static bed of our award winning K1 Micro® filter media.

The mechanically clean water then passes to the outside chamber of the nexus where the K1 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 protected surface area of each piece of the K1 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

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

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.

Flow Rates

One of the factors that can have a significant influence on the 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.
