Evolution Aqua Nexus Eazy 320 Lid
This rating applies only to the lid which is fully effective and reduces noise from the filter tanks to a minimum. I am just slightly gobsmacked that essential Eazy320s are able to be sold without their lids and more importantly without the outlet plumbing connectors essential to empty the filters. It is all the more surprising given the relative costs of the parts and the fact l was never told these parts would not come with the main items.

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.
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.
What is Effective Volume ? The effective volume is the quantity of water in your pond, plus an allowance for shallow and or ponds exposed to high levels of sunlight. Both of these situations will result in a higher than normal algae growth, and fish pollution. We advise that to ensure your that your equipment is correctly sized, the effective volume be considered the minimum size for the equipment you select. However do remember to check the details of the product you are interested in, to ensure that there are no other allowances or consideration specific to that product are required.
