Evolution Aqua Nexus 320 Filter

Nexus

The Nexus 220 filtration systems deliver dramatically improvedlevels of clarity for ponds. Building on the success of the award winning Nexusrange this new generation of filters cleverly combine mechanical and biologicalfiltration into one advanced filter system. whilst being incredibly easy toclean and simple to install.

 

The Nexus 220 features a re-designed Eazy filter which nowutilises the all new K1 Micro filter media. in a static bed. to deliverimproved levels of mechanical filtration. The Nexus filter systems also use theacclaimed K1 Media in the moving bed to deliver outstanding levels ofbiological filtration. Together this combination of filter media works todeliver crystal clear and healthy water.

 

All Nexus filtration systems can be installed on pump fed orgravity fed setups depending on your pond configuration. The Nexus 220 issuitable for ponds up to 18.000 litres (4.000 gallons) while for larger pondsthe 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 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 MicroMedia (20 litres in the Nexus 320 and 18 litres in the Nexus 220) which islocated within the inner chamber of the Nexus. After water enters the Nexus itrotates around the Eazy in the inner chamber with a downward motion allowingthe larger solids to settle to the bottom of the chamber before passing throughthe slots of the Eazy into the static K1 Micro. The water flows from all anglesthrough the K1 Micro where improved mechanical filtration and settlement takesplace and fine particles are caught within the K1 Micro. The water then flowsthrough 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. 100litres of K1 Media is supplied with the Nexus 320 with the option to add anextra 200 litres of K1 Media should it be needed. The Nexus 220 is suppliedwith 50 litres of K1 Media. with the option to add an extra 100 litres of K1Media if needed. This allows the biological capability of your filter to growwith your fish.

The outer chamber is where the final stage of biological treatmentoccurs. Biological breakdown occurs through different strains of bacterialiving on the protected surface area on each piece of the K1 Media. Thesebacteria convert Ammonia and Nitrite into harmless Nitrate. The amount ofAmmonia and Nitrite produced in the pond is dependent on feed rates and thetype of food used. For higher feed rates additional K1 Media should be addedinto the outer chamber.
