Cyanuric Acid (Stabilizer) Calculator

Protect your chlorine from UV degradation. Calculate the exact amount of CYA needed to maintain a stable sanitizing environment.

Quick Conclusion
To raise Cyanuric Acid (CYA) by 10 ppm in a 10,000-gallon pool, you need approximately 13 oz of granular stabilizer. Ideal range is 30-50 ppm for non-salt pools and 60-80 ppm for salt pools.

Pro-Tip

Draining is Necessary: Cyanuric Acid does not evaporate and is not consumed. The only way to lower high CYA is to drain a portion of your pool water and refill with fresh water. Avoid "Stabilized" chlorine (pucks/dichlor) if your levels are already at 50+ ppm.
