What is the ideal pH of hot tub water for chlorine?

A pH level within this range provides an environment where chlorine can work optimally, helping to prevent the growth of algae and harmful bacteria. If the pH level goes too high or too low, the efficiency of the chlorine can be compromised. 

Regular monitoring of the pH level and adjusting it as needed using pH increasers (pH+) or pH decreasers (pH-) can help maintain the ideal pH range for chlorine effectiveness in your hot tub water. It’s also essential to follow the specific guidelines provided by the hot tub manufacturer and regularly test the water to ensure proper sanitation and water quality.
