Description
Maintain perfectly balanced spa water with Master Clear pH Up. Low pH can cause acidic water, leading to equipment corrosion, reduced sanitizer effectiveness, cloudy water, and skin and eye irritation.
Master Clear pH Up uses a premium sodium carbonate (soda ash) formula that dissolves quickly and safely raises pH without affecting the enjoyment of your spa when used as directed.
Maintaining the proper pH range allows chlorine and bromine sanitizers to work at peak efficiency, helping keep water crystal clear while protecting heaters, pumps, plumbing, and acrylic surfaces.
Ideal for routine maintenance, fresh fills, and correcting low pH after heavy spa use or rainfall. Master Spas recommends maintaining pH between 7.4–7.6 with total alkalinity between 100–120 ppm for optimal water balance.
