Happy Hot Tubs - the best for your hot tub

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). PH Plus is also used to increase the Total Alkalinity of your Spa, Hot Tub or pool water. However, if needed to be raised accurately, we sell an Alkalinity Plus, please see our shop.

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