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.

Q1: What makes the Gemini CX different from a standalone controller?
Unlike standalone ORP systems, the Gemini CX is an integrated package that includes both the Gemini controller and a built-in salt or mineral chlorinator. It continuously analyses water quality and directly manages chlorine output for a fully automated sanitation solution.
Q2: Does the Gemini CX include pH control?
Yes, the Gemini CX comes with an integrated peristaltic dosing pump that automatically adjusts pH levels, ensuring your water remains balanced and comfortable for swimming while improving chlorine effectiveness.
Q3: Is it compatible with both salt and mineral pools?
Absolutely. The Gemini CX is designed to handle both saltwater and mineral water pool setups, making it ideal for almost any installation.
Q4: What are the main benefits of having an integrated chlorinator?
Because the chlorinator is built into the Gemini CX, there's no need to manage separate units or controls. The system automatically analyses, doses, and maintains sanitiser and pH levels, reducing effort while improving water quality and consistency.
Q5: What is the warranty?
The Gemini CX includes a 3-year manufacturer’s warranty when installed in domestic applications. Always confirm with your installer or authorised dealer for the latest coverage details.
