Rx Clear® Swimming Pool pH Minus

Rx Clear® pH Minus aids in preventing cloudy pool water and scaling by decreasing the pH level and alkalinity to their appropriate levels. Water pH levels should be kept in the range of 7.2-7.6 ppm. pH Minus is a more economical and safer alternative to using muriatic acid.

Directions:

• To lower alkalinity: pour in one spot of the pool water
• To lower pH: broadcast evenly over the pool's surface
