Product Information


This is a replacement Rainbow Cyanuric Acid Testing Reagent. This replacement reagent has a bottle size of 32 oz.

Reagent for testing Cyanuric Acid.

One of the most common chemicals used for the prevention of chlorine loss in swimming pools is Cyanuric Acid (also called CYA, Conditioner, or Stabilizer); it protects the free chlorine from being destroyed by the sun ultraviolet rays. If cyanuric acid is present in the water in sufficient levels, less chlorine degradation occurs. Keeping chlorine in the water longer will help to protect the swimmers in the pool.

Product Features

  • Cyanuric Acid testing reagent for Pentair/Rainbow test kits.
  • Ideal level of cyanuric acid is 30 to 50 ppm (parts per million).
