pH = Potential Hydrogen

Indicates the level of acidity or alkalinity of water on a scale ranging from 0-15. A low pH causes etched plaster, metal corrosion, vinyl liner wrinkles, and eye irritation. A high pH causes scale formation, chlorine inefficiency and eye irritation. The ideal range for pH in swimming pools is 7.4 to 7.6.
Make sure to have your pool water tested by a professional at least twice a year. The “pool store” will do a more in depth test than the homeowner test kit can. Always “Free Water Testing” at the Above Ground Pool & Spa Company.
