What the Heck is the LSI? (And How to Stop Fighting the Water)

Goal: To shift the focus of pool service professionals from chasing arbitrary chemical ranges to mastering the Langelier Saturation Index (LSI) for predictable, damage-free water. Description: For years, the industry has relied on standard parameter brackets that often force unnatural water conditions and constant chemical adjustments. This session shatters that old approach by introducing the LSI as the ultimate, objective measurement of water balance. Attendees will discover exactly why pools scale or etch, the undeniable impact of Henry's Law on rising pH, and how to leverage the Orenda app to make precise, science-backed adjustments. It is a practical guide designed to help technicians stop wasting chemicals, end the frustration of yo-yoing chemistry, and start protecting surfaces year-round.
