Item Package Quantity:1 The SpaPure pH Down effectively lowers the pH level of spas and hot tubs. This granular product helps maintain the proper proper pH level maintained between 7.2 - 7.6. This product takes action if the pH level exceeds 7.6, which if that level is reached then the water can become cloudy and corrosive, which can cause scale buildups. It is compatible with chlorine, bromine, biguanide, silver-mineral, and ozone-treated spas.
