Use this high quality PH Plus to increase the PH value of the water in your spa (7.2 to 7.6 is the optimum for spas).

If PH is too low, staining or corrosion may occur. PH Plus is also used to increase the Total Alkalinity of your Spa, Hot Tub or pool water. Looking for a more specific Alkalinity Increaser? View our TA Plus.

Simply Test Your Hot Tub or Swimming Pool water and follow the instructions to increase your PH correctly.
