Calcium Flakes in Saltwater Pools
If you own or maintain a saltwater pool, there's a good chance you have seen calcium flakes in it too. This article will explain what the flakes really are and debunk some myths about them. Let's get into it.

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 forms of calcium carbonate that we commonly find in swimming pools. They are carbonate scale, calcium crystals [calcite], and the topic of today’s article, calcium dust.
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.
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.
