The rate of CHLORINE loss (pounds of chlorine per hour) due to UV degradation will depend on a number of factors, including the size of the AQUATIC VENUE, the depth of the water and the intensity of the sunshine. It will also depend on the concentration of cyanuric acid present, since cyanuric acid can help prevent the decomposition of CHLORINE by UV. Given the number of variables, it is difficult to predict CHLORINE decomposition rates in specific AQUATIC VENUES.
