Product Description

The 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 features 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).

Nexus 220 & 320 Specifications

How the Nexus works

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.

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 harmless 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 (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 - K1 Moving Bed

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 the biological capability of your filter 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.

AirPump Requirements

You can increase the biological capacity of your Nexus by adding additional K1 Media into the outer chamber. You will however need to ensure that you have the correct size of air pump to enable the K1 Media to move sufficiently (see table for recommended size of air pump).

For Nexus filtration systems straight out of the box with no additional media added, we recommend an Air Pump 75 to power the moving bed in a Nexus 220 and an Air Pump 95 for a Nexus 320.

Installation

Nexus filtration systems can be installed on PUMP FED or GRAVITY FED set-ups. In all circumstances the Nexus MUST be installed on a solid, level base, a minimum of 1.2 metres x 1 metre.
 

Pump Fed Set-Ups

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).

Pump Fed Set-Ups

Gravity Fed Set-Ups

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.

Nexus Back Wash Instructions

From time to time, it may be necessary to carry out a back wash of your Nexus. This is a simple operation which can be done during your normal cleaning procedure.
