SUN® - Water Chemistry Problems - Chlorine Stabilizer

PROBLEM:  High stabilizer levels (above 200)

POSSIBLE CAUSES:  Long-term use of stabilized chlorinating products (including shock products) or excessive additions of cyanuric acid stabilizer.

SOLUTION:  Levels over 200 ppm may need to be lowered to 40 ppm. The only way to lower cyanuric acid is to replace some of the pool water with fresh water. Always remove an amount of water that avoids possible vinyl liner shrinkage or structural damage (1-2 feet at a time is usually a safe amount).

PROBLEM:   Low stabilizer levels

POSSIBLE CAUSES:  Insufficient dosage of cyanuric acid or replacement of all or part of the water through draining or backwashing.

SOLUTION:  Low levels of cyanuric acid can easily be increased by the addition of a conditioner. Add SUN Conditioner according to the label directions. Cyanuric acid will have a slight lowering effect on the pH; test and adjust if necessary.
