pH Minus is used when your pH levels are reading too high.

It is important to maintain a pH level of 7.2 to 7.4 to avoid scale build up within your hot tub and to ensure that your disinfectant (chlorine or bromine) is able to work effectively.

Once the product has been added following the dosage instructions on the label, you should then run your jets for a full cycle to allow it to be evenly dispersed through the water.
