Carbon Dioxide for Pool pH Control

Carbon Dioxide for Pool pH Control is a practical field guide for pool technicians, aquatic facility operators, consultants, and maintenance professionals responsible for managing commercial swimming pools and spas. For decades, carbon dioxide has been used as an alternative to mineral acids for pH control. Yet the technology remains surrounded by folklore. Operators are told that CO2 causes runaway total alkalinity, consumes excessive gas, cannot cope with heavy bather loads, or is too difficult to install and manage. This book examines those claims from both a practical and scientific perspective. Drawing on more than forty years of field experience and hundreds of real-world installations, David Watson explains how CO2 systems actually behave, where they work well, where they struggle, and why many commonly reported problems have little to do with carbon dioxide itself.

The chemistry and physics are explained in plain language, with practical examples, installation guidance, troubleshooting procedures, checklists and calculators designed for immediate application.

CO2 is not the problem. Understanding the system is.
