It is widely known that pH controls the strength and efficacy of chlorine. And that's true, except when Cyanuric Acid (CYA) is in the water. CYA changes the entire dynamic, and that's what we discuss in this article.
Our Fourth and final Pillar is to minimize cyanuric acid (CYA). Maintaining CYA at a manageable level can be a struggle, and we realize that. But CYA has a major impact on chlorine efficiency. It can be summarized in two words: avoid over-stabilization. This article will explain what CYA is, why we use it, how it gets into our water, and how to manage it to prevent over-stabilization.
High levels of Cyanuric Acid (CYA) in pool water can cause issues with both water quality and water balance. Overstabilization slows chlorine down and lowers the LSI, making water more aggressive. Because of these reasons and more, keeping CYA to a minimum is our Fourth Pillar of Proactive Pool Care.
