pH is one of the most important factors in balancing your water. Low pH levels can lead to corrosion of metal parts and equipment, etched plaster, eye and skin irritation and wrinkled vinyl liners. High pH levels can lead to scale formation on pool surfaces and equipment, and cloudy water.

To adjust the level when it is too high, add Aqua Chem pH Decreaser (dry acid) to the pool water; when the pH level is below the acceptable limit, use pH Add.
