Rx Clear® pH Plus is made of 100% sodium carbonate also called Soda Ash. This pH plus neutralizes acidic water, eliminates corrosion and improves the effectiveness of chlorine. Rx Clear® Swimming Pool pH Plus corrects problems associated with low water pH, it can be used in both pools and spas, and is compatible with salt water pools. Test your pool water weekly to keep the perfect pH level in your pool for maximum comfort.
Pevents corrosion of metal surfaces such as light fixtures, railings, ladders, screws, pool cover components, pool heater components, and metals in your pump or filter. Also prevents etching, pitting, and delamination of concrete, plaster, gunite, shotcrete, and fiberglass pools.
Use 1-2 lbs. for every 10,000 gallons until pH reaches the proper level.
