“LSI Balance and Calcium Management is the first of Orenda’s Four Pillars. This is arguably the most important of the Four Pillars because it is about understanding water and how it behaves.
We need to come together and understand how calcium behaves in water. Let’s start by debunking a myth in the pool business: calcium is NOT your enemy! It is actually your best friend. Yes! Calcium does amazing things for water chemistry, and helps pool owners and operators balance their pools according to the LSI. The LSI (Langelier Saturation Index) is a measurement of calcium carbonate (CaCO3) saturation in water. Too much (high LSI over +0.30) can lead to calcium falling out of solution as scale. Too little (low LSI below -0.30) means your water is aggressive and looking for calcium to consume. This is the cause of etching, corroded pool equipment and many other problems.
When the pool is properly balanced with calcium, other factors of water chemistry become surprisingly easy to manage. Factors like pH and total alkalinity seem to stay more consistent. Understanding how calcium behaves means we can predict and control it. Say goodbye to scale and etching!”
