Hammerhead Pools is a pool care company servicing New Orleans, Louisiana. We take pride in the water in your pool. Hammerhead Pools uses the Langelier Saturation Index (LSI) to ensure the water is safe and balanced. LSI is the measurement of water balance. It combines all of your readings into one score. That score determines if your water is aggressive/corrosive (low LSI), balanced, or scale-forming (high LSI). What that means in it's most basic form, is that if your LSI is high for an extended period, you will encounter plaster damage. If it is too low, your pool will form that ugly white scale. Not only is it unattractive, but it forms inside of your equipment and will damage them as well. Hammerhead pools checks your LSI score on every visit and keeps it in a balanced range so you don't incur any damage.
