Why Is pH Balance Important?
Maintaining the correct pH level is an important part of swimming pool and hot tub maintenance.
High pH levels can contribute to cloudy water, scale formation and reduced effectiveness of certain water treatment chemicals.
Our pH Minus products help lower elevated pH levels when used according to the product instructions.
Always test your water before adding chemicals and follow the dosage and safety instructions on the product label.
