Gemini CX – Controlled Salt (or Mineral) Sanitation System with pH Control

All-in-one precision sanitation with integrated pH control

The Gemini CX from Pool Controls combines the precision of an ORP-controlled system with the convenience of built-in salt or mineral chlorination—all in one package. Using a multi-electrode probe, it continuously analyses your pool water and automatically adjusts chlorine production through its integrated chlorinator to maintain perfect sanitiser levels.

The system also features integrated pH control via a dedicated peristaltic dosing pump, ensuring your pool stays perfectly balanced without constant manual intervention. Whether your pool uses salt or mineral water, the Gemini CX offers hassle-free automation, crystal-clear water, and smarter sanitation in a single, streamlined solution.

Key Features

  • All-in-one sanitation system: combines ORP-controlled automation, an integrated salt or mineral chlorinator, and pH management.

  • Integrated pH control: built-in peristaltic dosing pump ensures your pool’s pH stays balanced with minimal manual intervention.
  • Salt or mineral pool compatible: supports both water types for flexible installation and performance.
  • Low-maintenance, smarter operation: simplifies pool care by combining multiple automation systems into one intelligent controller.
