Cold Water and the LSI
After the initial fill/startup, the vast majority of damage done to a swimming pool occurs during the winter. This is because cold water lowers the LSI, making water more aggressive. In other words, etching and corrosion are more likely to happen in cold water.
Understanding LSI: The Langelier Saturation Index
The Langelier Saturation Index (LSI) is a cornerstone of the Orenda program. The LSI is the unbiased measurement of water balance, as defined by calcium carbonate saturation. It determines if our water is aggressive/corrosive (low LSI), balanced, or scale-forming (high LSI). It sounds simple enough, but let's dive in and show you just how much it matters to other aspects of water chemistry.
