The One on pH

Ask a question here

In this episode of the Talking Pools podcast, Rudy Stankowitz dives deep into the essential aspects of pool water chemistry, focusing primarily on pH. He emphasizes the importance of understanding pH as the core of water chemistry, explaining how it influences chlorine effectiveness, the role of alkalinity, and the buffering systems that stabilize pH levels. Rudy discusses the impact of electrolysis, CO2 behavior, and the Langelier Saturation Index on pH management. He also highlights the challenges of accurate measurement and the biological influences on pH. The episode concludes with practical takeaways for pool professionals to master pH control and maintain balanced water.

takeaways

• pH is the most influential factor in pool water stability.
