Evolution Aqua Nexus Automatic Pump Fed System

Pump Fed Cleaning Cycle

■ Adjustable timer kicks in to start a cleaning cycle.

■ Control box automatically switches circulating pump off.

■ The water level in the Nexus equalises

■ Air is diverted from the outer bio-chamber to the Eazy to clean the media.

■ After the media inside the Eazy has been cleaned, the automated waste valve opens.

■ Eazy is drained to waste.

■ The automated waste valve closes.

■ Air is diverted back from the Eazy to the bio chamber.

■ Circulating pump is switched back on.

■ Nexus returns to filtration mode.

The generally accepted practice is that when you keep ornamental fish, whether in a pond or in an aquarium, to keep the water fresh, 10% of the volume of the water in the pond/aquarium should be changed on a weekly basis. With this in mind, we recommend that you set your Nexus Automatic system to run a cleaning cycle so as to exchange water in line with this. The general parameters of our ponds are the turnover rate. This is the time that it takes for the total volume of the pond to pass through the filter system once. We recommend that for ideal performance a turnover rate of every 2 to 3 hours is found to be best.
