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 in the inner chamber "Eazy" filter, in a static bed, to deliver improved levels of mechanical filtration. The Nexus filter systems also use the acclaimed original 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. (pump not included)

The Nexus 220 is suitable for ponds up to 18,000 litres (4,000 gallons) while the Nexus 320 can be installed on for 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 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 the 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.



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.

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