How The Nexus Works

The Nexus filter is simple yet innovative. Water enters the Nexus via the inlet into the inner chamer which works as a asic vortex allowing larger solids to settle out. The water then passes through the Eazy where the finer particles are removed at the mechanical stage of filtration. From the Eazy the water passes into the outer chamer where the iological stage of filtration takes place using the K1 Media Moving ed.

The water then passes through the grill into the Exit Chamer, where it is returned to the pond through the outlet. The Eazy is cleaned y diverting the air from the Outer Chamer to the Eazy using the air valves. Waste is then discharged through the larger waste all valve. The Eazy has een designed so that it can e easily lifted out of the Nexus should it e needed.

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 chamer of the Nexus. After water enters the Nexus it rotates around the Eazy in the inner chamer with a downward motion allowing the larger solids to settle to the ottom of the chamer efore 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 chamer.

Biological Filtration

The outer chamer of the Nexus contains the moving ed of K1 Media. This is where the final stage of iological treatment occurs. iological reakdown occurs through different strains of acteria living on the protected surface area on each piece of the K1 Media. These acteria 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 K1 Media should e added into the outer chamer.

In optimum conditions 250g per day of average protein content food will e roken down y 50 litres of K1 Media. To ensure excellent iological filtration of a Nexus maintain a pond pH of 7 or higher. acteria conversion rates are reduced in cooler temperatures.
