Achieving perfectly balanced pool water is an ongoing endeavor, and understanding the interplay between key chemicals is fundamental. Among the most important is the relationship between Cyanuric Acid (CYA) and free chlorine. At NINGBO INNO PHARMCHEM CO.,LTD., we emphasize the importance of this balance for effective sanitation and water clarity.

Cyanuric Acid, as a chlorine stabilizer, is designed to protect chlorine from being rapidly degraded by sunlight. However, when CYA levels are too low, your chlorine becomes highly vulnerable, leading to rapid loss of sanitizing power. Conversely, excessively high CYA levels can create 'chlorine lock,' where the chlorine, though present, becomes less effective at killing harmful microorganisms. This is why maintaining the right balance is crucial.

The ideal range for CYA in most swimming pools is between 30 to 50 ppm. This range provides sufficient protection for chlorine without significantly hindering its sanitizing activity. The recommended ratio of free chlorine to CYA is often cited as around 7.5%. For example, if your CYA level is 40 ppm, your free chlorine level should ideally be around 3 ppm. This ensures that you have enough active sanitizer to combat contaminants while being protected from UV breakdown.

Troubleshooting Common Issues:

  • Low CYA: If your CYA levels are low, your chlorine will likely be consumed quickly, especially in sunny conditions. You'll need to add more CYA to stabilize the chlorine.
  • High CYA: If your CYA is too high, you might notice that your chlorine tests show adequate levels, but your pool still experiences algae growth or cloudy water. The only reliable method to lower CYA is by partially draining the pool and refilling it with fresh water. It's advisable to stop adding stabilized chlorine sources until your CYA levels are back in range.
  • Chlorine Fluctuations: Even with correct CYA levels, other factors like bather load, temperature, and organic contamination can affect chlorine levels. Regular testing and appropriate adjustments are always necessary.

NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality Isocyanuric Acid that can be used to maintain these optimal levels. By diligently monitoring your pool's CYA and free chlorine, you can ensure a consistently safe, clean, and enjoyable swimming environment. Proper balancing of cyanuric acid and chlorine is a cornerstone of effective pool care.
