Leisure Time Spa Up raises pH and total alkalinity levels in hot water. This spa care product puts alkalinity and pH up to levels in the range where the sanitizer is more effective. Increasing the pH of spa water can help prevent corrosion and the formation of scale. This pH increaser will help you maintain proper levels of your hot tub chemicals so that you can relax and enjoy your spa whenever you need, helping you feel renewed and rejuvenated. It is important to maintain the pH in your hot tub between 7.2 - 7.8; a low pH reading (below 7.2) can cause equipment corrosion or scale formation.
