Range Chemistry & the LSI Reality Check

Ask a question here This Friday episode digs into one of the most argued topics in pool care: range chemistry and the Langelier Saturation Index (LSI). Rudy takes us back to 1936 and the work of Wilfred F. Langelier, who developed a model to prevent municipal water pipes from dissolving or scaling shut. LSI was never designed for swimmers. It was built to answer one simple question: Will this water dissolve calcium carbonate… or deposit it? That’s it. Pools adopted LSI later because plaster b...
