What are the chemical requirements for maintaining a safe public pool environment?

California State Requirements: 

 pH of 7.2 - 8.0 (recommended 7.4 - 7.6) 

 Cyanuric acid amounts less than 100 ppm  Spa temperature may not exceed 104°F Not State required but recommended: 

 Temperature of pool around 76°F – at temperatures between 78°F and 82°F, chlorine dissipates faster, algae grows better, and the formation of scale is more likely to occur so it is recommended that the temperature of swimming pools remains outside this zone. 

 Alkalinity of 80-120 ppm
