Our water chemistry program defies swimming pool industry standards, textbooks, and pool stores. This article explains why we are different.

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. This article aims to simplify chemistry, so it can be more easily understood. If you are a chemist (who is not already familiar with this subject) and you would like to get more in depth on the science of this topic, this is one of our primary sources. We will link to other external sources in this article as well. So let's get into it.

There are three distinct types of calcium carbonate (CaCO₃) commonly found in swimming pools: calcium carbonate scale, calcium (calcite) crystals, and various forms of calcium dust. This article focuses on calcium dust.
