What does the term "CYA" stand for in pool chemistry?

The term "CYA" in pool chemistry stands for Cyanuric Acid. Cyanuric Acid is commonly used in swimming pools as a stabilizer for chlorine. It helps to protect chlorine from being broken down by the sun's ultraviolet (UV) rays, allowing for more efficient and effective use of chlorine to sanitize the pool water. Regularly maintaining the appropriate levels of Cyanuric Acid in a pool is crucial, as it helps in prolonging the effectiveness of chlorine, thereby reducing the need for frequent additions of chlorine and improving overall water quality.

Understanding the role of Cyanuric Acid in pool maintenance is essential for maintaining proper chemical balance, which directly impacts swimmer safety and overall cleanliness of the pool. While other terms listed might relate to different aspects of pool chemistry, they do not accurately represent the acronym "CYA."
