3 Types of Calcium Dust in Swimming Pools
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.

What are you going to do if you remove a winter pool cover and find calcium crystals in the pool? If you have encountered winter crystals in the past--and you may have thought it was 'scale'--what did you do in the past? Did it work? This article will outline four things Orenda recommends if you are trying to open a pool with crystals in it.
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.
Carbonate Scale is a buildup of hardened calcium carbonate (CaCO3) on pool surfaces or equipment. Scale can be a big problem for a pool and its plumbing system (and other water systems besides pools, like fountains).
