Product Information


Sunnys pH up is a fast acting, quick dissolving product that will quickly and effectively raise the pH in your hot tub water. pH is a measure of the acidity of the water. pH should be maintained at 7.2 to 7.6 for optimal sanitizer effectiveness, protection of hot tub parts and equipment, and user comfort. If the pH drops below 7.2 the water is too acidic. This can corrode the spas parts and equipment and cause eye and skin irritation. If the pH is above 7.6 the water is too base or alkaline. The sanitizer will lose some effectiveness, and minerals can fall out of solution which can cause cloudy water, scale build up (the feeling of sand paper on the spa shell) and equipment damage. Maintaining the proper pH level in your hot tub is important to maintain a safe, clean and healthy spa.  pH up is compatible with chlorine, bromine, biguanide, silver-mineral, and ozone-treated hot tubs.
