Carbon Dioxide for Pool pH Control

CO₂ for Swimming Pool pH Control - Explained Properly

Most pool operators have heard conflicting things about CO₂ systems.

Some call them unreliable. Others say they raise alkalinity. Many simply avoid them.

This book cuts through the confusion.

This is a practical, field-based guide to understanding, installing, and operating CO₂ systems in real-world swimming pools.

Rather than repeating industry folklore, this book explains what actually happens - and why.

Inside, you'll learn:

• • How CO₂ really affects pH and why it does not increase total alkalinity
  • The difference between CO₂ and acid systems in real operating conditions
  • How to install and tune CO₂ systems for stable, predictable performance
  • Where CO₂ works well - and where it doesn't
  • How to avoid common mistakes that lead to poor results

Written from decades of hands-on experience, this is a guide for operators, technicians, and engineers who want to understand the system - not just follow instructions.

This is not a theoretical book.

It is written from practical experience, supported by clear explanation of the underlying chemistry and system behaviour.

The goal is simple: reduce guesswork and improve decision-making in the field.

Endorsement

"This book is a practical guide to using CO₂ systems correctly on swimming pools. Two things in particular stick out in this book that make me highly recommend it to readers: 1) It debunks myths (called folklore in the book) about CO₂; particularly that CO₂ systems increase total alkalinity, and 2) It gives practical guidance for installing and operating CO₂ systems safely. Every commercial pool operator should read this and decide if CO₂ systems are right for their facility. Well done, David."

- Eric Knight

If you work with commercial pools and want a clear, practical understanding of CO₂ systems, this book will give you the tools to make informed decisions.
