Maintaining a chlorine residual is an important part of water chemistry in swimming pools, however, this may not be as easy as it sounds. One of the most common pool problems is excessive sanitizer loss, and this can be caused by a few things. The most common issue is low or no cyanuric acid (also known as stabilizer or conditioner).
Cyanuric Acid (CYA) is designed to protect chlorine from being destroyed by sunlight. When chlorine is exposed to intense sunlight and UV rays, and it will degrade by at least 90% in just 2 hours. CYA is an important part of swimming pool water chemistry as it is designed to protect the chlorine. The more protection for the chlorine, the more protection for swimmers as the chlorine can then work to kill disease and bacteria. Studies have found that it takes 10ppm of cyanuric acid to protect up to 1.5ppm of chlorine, therefore, any excess chlorine (over 1.5ppm) is not protected with only 10ppm of CYA. The recommended level of CYA is 30-50ppm and this will give adequate protection to chlorine when the sanitizer level is between 1-5ppm.
To protect chlorine from sunlight, Natural Chemistry has you covered with Instant Pool Water Conditioner!
Natural Chemistry's Instant Pool Water Conditioner® is a liquid used for stabilizing chlorine from UV sunlight loss. It begins working to protect chlorine the instant it is added to the pool. Regular cyanuric acid with a pH of 2.8 is very acidic and it takes from 4 to 7 days to dissolve. This can cause damage to the pool surface or circulation system, depending on the method of application. Instant Pool Water Conditioner is not an acid (it's a salt) and has a pool friendly pH, so it will not damage pool surfaces or equipment.
