pH Down

pH is most important for maintaining crystal clear swimming pool water. High pH will cause eye and skin irritation, waterline tile scale deposits, and an unhappy pool owner. Low pH will cause the same eye and skin irritation, but will also, etch the swimming pool plaster, fiberglass, and vinyl liner, which will also cause an angry and unhappy pool owner.

 

pH Down, otherwise known as dry acid, will lower your pH to levels that are most efficient for crystal clear water.
