Ideal Cyanuric Acid Levels

Ideal cyanuric acid levels should be between 30-50 ppm. CYA levels exceeding 70 ppm can reduce the effectiveness of your chlorine.

Product Information


This is a Pentair Rainbow #79 Specialty Test Kit for Cyanuric Acid/Turbidity using a slide calibrated test stick and reagent. The reagent in this kit is 8 ounces. This kit includes instructions.

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

  • Tests for Cyanuric Acid
  • Reagent is 8 ounces 
  • Reagent: Cyanuric Acid Test

Instructions for Cyanuric Acid Test

1. Slide calibrated test stick to bottom of the tube.

2. Fill tube with pool water to line A on test stick.

3. Fill tube to line B with test reagent.

4. Mix by moving test stick up and down 10 or 12 times, leaving test stick on bottom position.

5. Allow the solution to set for about 2 minutes before continuing the test.

6. Read out is made by looking down through solution from top of test tube to observe black dot. If black dot cannot be seen, raise test stick above water level and then lower it carefully until black dot just disappears. Then read through clear tube the number on the front of the test stick closest to water level. This will be your reading expressed in parts per million of cyanuric acid to million parts of water in swimming pool.
