What is the potential impact of high levels of cyanuric acid in swimming pools?

• A. It can improve water clarity
• B. It can reduce chlorine’s effectiveness
• C. It leads to increased water temperature
• D. It promotes algae growth

Answer: (B)

High levels of cyanuric acid in swimming pools primarily serve as a stabilizer for chlorine, protecting it from rapid degradation due to sunlight. However, when the levels of cyanuric acid become too elevated, it can significantly reduce the effectiveness of chlorine in sanitizing the water. The balance between chlorine and cyanuric acid is crucial; optimal levels of cyanuric acid range from 30 to 50 parts per million. When cyanuric acid levels exceed this range, it can lead to diminished chlorine activity, meaning that even though there may be sufficient chlorine present, its ability to kill bacteria and other pathogens is severely compromised. This situation poses health risks, as inadequate disinfection can lead to the spread of waterborne illnesses. By contrast, the other options present misconceptions about cyanuric acid's function. While some might think increased cyanuric acid improves water clarity, it does not directly influence clarity itself. Instead, it stabilizes chlorine. Additionally, it does not lead to increased water temperature nor does it promote algae growth under normal circumstances; rather, ineffective chlorine levels due to high cyanuric acid could inadvertently contribute to algae growth if not properly managed.
