Cyanuric Acid (CYA)

Cyanuric Acid, sometimes referred as CYA, is a chlorine stabilizer for swimming pools and has been designed to reduce chlorine loss caused by the sun’s ultraviolet rays. CYA is found in pool granules or tablets, sometimes labeled as Dichlor and Trichlor, or sold individually as a pool stabilizer, and is widely used and necessary in outdoor swimming pools .

Having CYA in moderation helps your chlorine work to sanitize the water. But if your CYA is not balanced correctly, problems will start to occur. Too much CYA will inhibit the chlorine from working and will increase the amount of time it takes to kill bacteria. Too little CYA and the chlorine will be broken down by the sun’s UV rays.

The ideal level for CYA is between 30‐50 ppm for fresh water pools and 60-80 ppm for salt water pools. In the past, when the CYA levels built up in the pools water, it was recommended to drain 1000’s of gallons of pool water and refill it to offset the CYA levels. Today, it is no longer necessary to pump good water into our drains.

Let the GUARDIAN H2O CYA Remover help maintain your CYA levels to ideal levels and keep your pool crystal clear.

Too much or too little pool stabilizer (Cyanuric Acid) may cause your pool to allow algae growth. CYA levels should be tested regularly to ensure your chlorine is working optimally to sanitize the water

Balanced CYA

Potentially too high / low CYA
