CYA is a pool balancing product used to help chlorine last longer. The longer chlorine is present in pool water, the longer it’s available to kill bacteria and sanitize the water. In the pool industry, Cyanuric Acid is known as chlorine stabilizer or pool conditioner. 30-50ppm range recommended for non-saltwater pools. And if you live in an area where your pool gets a lot of direct sunlight, you may even consider bumping your cyanuric acid up to 80-100 ppm.

Cyanuric acid—also called CYA, pool stabilizer, or pool conditioner—is a weak acid that protects your chlorine from the sun’s ultraviolet rays, allowing it to work for much longer periods without constant top-ups
