What Is LSI?
The Langelier Saturation Index (LSI) predicts whether pool water will be scale-forming or corrosive.
LSI measures factors like pH, temperature, calcium hardness, and alkalinity to determine the potential for scaling or corrosion. A positive LSI means the water is scale-forming, while a negative value indicates corrosive tendencies. Hitting the sweet spot at 0 LSI keeps water perfectly balanced – neither scaling nor corroding.
Using LSI helps prevent ugly scaling, harmful corrosion, cloudy water, and excessive chemical use. It’s the smart way to optimize your pool water chemistry.
