Evolution Aqua Nexus 220+ / 320+ Automatic Cleaning Kit – Pump Fed
Automatic Cleaning Upgrade for Pump Fed Nexus 220+ and 320+ Filters
The Evolution Aqua Nexus 220+ / 320+ Automatic Cleaning Kit – Pump Fed automates the cleaning cycle of compatible pump fed Nexus filtration systems. Instead of manually closing ball valves, switching pumps off and adjusting air flow, the system controls each stage through a programmable control unit.
This kit fits Nexus 220 and Nexus 320 filters manufactured from 2006 onwards. The newer Nexus 220+, Nexus 320+, Nexus 220+ Ti and Nexus 320+ Ti models are supplied auto ready, which allows straightforward installation of the automatic cleaning system.
Once installed, you can programme cleaning cycles at fixed intervals. Alternatively, you can activate a cycle manually whenever required. Therefore, the filter maintains consistent mechanical performance while significantly reducing hands on maintenance.
How the Pump Fed Automatic Cleaning Cycle Works
The pump fed version follows a structured cleaning sequence to maintain efficient Eazy chamber performance.
Firstly, the timer activates the cleaning cycle. The control box immediately switches off the circulation pump, which stabilises water levels inside the filter.
Next, the system redirects air from the biological chamber into the Eazy chamber. As a result, the increased air agitation lifts and separates trapped solids from the K1 Micro media.
Once agitation completes, the automatic waste valve opens and discharges dirty water to waste. During this stage, the Eazy chamber drains fully, ensuring thorough debris removal.
After flushing finishes, the waste valve closes. Finally, the circulation pump restarts and the Nexus returns to normal filtration mode.
Because the system manages each stage electronically, it delivers consistent cleaning performance and removes reliance on manual operation.
Compatibility and Installation
This kit works with pump fed Nexus 220 and Nexus 320 filters manufactured from 2006 onwards. However, it is not suitable for gravity fed systems.
The Nexus 220+ and Nexus 320+ models come auto ready, so installation remains straightforward.
The cleaning interval is factory set to every 3 days. Nevertheless, you can adjust the frequency depending on fish stocking density, feeding levels and seasonal waste production. For example, heavily stocked koi ponds may benefit from more frequent cleaning during peak feeding periods.
By automating the Eazy chamber cleaning sequence, the Nexus Automatic Cleaning Kit – Pump Fed maintains stable mechanical performance and significantly reduces manual intervention.

Maintenance and compatibility checks
It is worth checking the supporting parts at the same time as the main product. Hose size, pressure pipe, valves, unions, UV units, filter inlets, air manifolds, spares and cleaning access can all affect how well the final system works. A correctly matched installation usually performs better and is easier to maintain than one built from parts chosen separately.
- Match the pump flow to the filter and pond volume, allowing for head height and pipework losses.
- Keep unions, valves and waste outlets accessible for cleaning and maintenance.
- Use suitable hose, pressure pipe or DN discharge pipework where specified by the manufacturer.
- Check compatible UV bulbs, quartz sleeves, media and spare parts before the pond season starts.
Plan this product as part of the complete filtration layout, rather than as an isolated item. Check the recommended flow rate, inlet and outlet sizes, waste connection, access for cleaning and the space needed for routine servicing before installation. A well matched filter system is easier to maintain and gives more reliable water clarity over the long term.
