An ideal level of Cyanuric Acid will make chlorine more stable when exposed to ultraviolet rays (sunlight), protecting against dissipation.
Dip an AquaChek Cyanuric Acid test strip in your pool or spa water for one second and remove it immediately. Test results in seconds with just one dip!
For a clean and healthy pool, test the water at each end a minimum of twice a week!
*Note: a minimum of 2 bottles of strips must be ordered
