PH Increase

Pool Master pH Increase is a reliable solution for raising the pH in swimming pools, spa pools, and hot tubs when levels fall too low. Maintaining the correct pH range (7.2–7.8) is essential for bather comfort, effective sanitation, and protecting pool surfaces and equipment from corrosion. This easy-to-use product dissolves rapidly, ensuring swift adjustment and even distribution.

• Safely raises pH levels for optimal water quality
• Helps protect pool equipment and surfaces
• Suitable for use in pools, spas, and hot tubs
• Fast-dissolving and convenient application
• Trusted by NZ pool professionals

Directions: Always test and adjust total alkalinity before pH. Add pH Increase directly to water as directed on the packaging. Run circulation for even distribution and retest after 2–4 hours.
