In this episode of the Pool School Podcast, host Roy "Al. G." Free dives into the often-overlooked yet crucial aspect of pool water chemistry: Understanding Carbonate Alkalinity in Pool Care. While most pool owners are familiar with total alkalinity, the specific role of carbonate alkalinity and its importance in stabilizing pH often goes unnoticed. This episode breaks down everything you need to know about carbonate alkalinity, from its definition and how it’s calculated to its vital role in maintaining a balanced and comfortable swimming environment.

Al. G. explains how carbonate alkalinity is a subset of total alkalinity, excluding the influence of cyanuric acid, and why this distinction matters for effective pool care. The episode provides step-by-step guidance on calculating carbonate alkalinity and demonstrates how proper levels can serve as a buffer to prevent pH from fluctuating, which can cause discomfort for swimmers and damage to pool surfaces and equipment.

Listeners will learn how to manage carbonate alkalinity by adjusting it through chemicals like sodium bicarbonate and muriatic acid, and how these adjustments can help keep pH stable. The episode also highlights the importance of carbonate alkalinity in saltwater pools, where it plays a significant role in maintaining pH stability and preventing issues like CO2 outgassing, which can otherwise destabilize pH levels.

Whether you're a pool professional or an owner managing your own pool, this episode will provide practical advice on maintaining proper carbonate alkalinity, ensuring your pool stays balanced, efficient, and safe for swimming. Tune in to learn how to optimize your pool chemistry for the best performance and long-term health of your pool!
