What is the ideal chemical balance for a commercial swimming pool?

Commercial pools should maintain Free Chlorine at 2.0-4.0 ppm, pH between 7.4 and 7.6, Total Alkalinity between 80 and 120 ppm, Calcium Hardness between 200 and 400 ppm, and Cyanuric Acid between 30 and 50 ppm (or 0 for indoor pools).

How does cyanuric acid (CYA) protect pool chlorine?

CYA acts as a sunshield for free chlorine molecules. Without CYA stabilizer, ultraviolet radiation from the sun degrades up to 90% of free chlorine in outdoor swimming pools within two hours.
