It is important to check the pH on a regular basis. The pH will be affected by the bather load, the addition of new water, the addition of various chemicals, and the type of sanitizer used. Please follow these guidelines:
- Arctic Spas recommends a slightly higher pH range for your spa water; 7.2–7.6.
- The pH level is the measure of acidity and alkalinity. Values above 7 are alkaline; those below 7 are acidic. Maintaining the proper pH level is extremely important for: • Optimizing the effectiveness of the sanitizer. • Maintaining water that is comfortable for the user. • Preventing equipment deterioration.
- If the spa water’s pH level is too low, the following may result: • The sanitizer will dissipate rapidly. • The water may become irritating to spa users. • The spa’s equipment may corrode. If the pH is too low, it can be increased by adding Arctic Pure® Adjust Up to the spa water.
- If the pH level is too high, the following may result: • The sanitizer is less effective. • Scale will form on the spa shell surface and the equipment. • The water may become cloudy. If the pH is too high, it can be decreased by adding Arctic Pure® Adjust Down to the spa water.
