The Nexus Automatic System will control the cleaning cycle fully automatically. Cleaning is done on a timer, which is factory set to clean once every 3 days, however, this is easily adjustable to fit in with your pond requirements. The Nexus Automatic System will run a cleaning cycle which lasts approximately 10 minutes.

Gravity 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.
  • Inlet valve closes whilst at the same time air is diverted from the outer bio chamber to the EAZY to clean the media.
  • After the media has been cleaned, the waste valve opens.
  • EAZY is drained to waste and inlet valve opens for a final flush of the EAZY.
  • The waste valve closes.
  • Air is diverted back from the EAZY to the bio chamber.

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.general parameters of our ponds is turn over 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 turn over rate of every 2 to 3 hours is found to be best.
