Scale-Forming Tap Water

We recently had to adapt the Orenda Startup for a unique tap water situation.

Most tap water we test is low on the Langelier Saturation Index (LSI). On the Orenda app, it shows up with a red LSI number at the bottom. And by "most tap water", we mean almost all tap water in the country. That is, until the water we tested recently in the Bay Area of Northern California. It had a purple LSI.

I knew nothing about pool plaster. So I went to the NPC Show.

I have never plastered a pool in my life. In fact, until this week, I had never even seen pool plaster being applied. To be honest, I did not even know the difference between plaster, cement, gunite, concrete, shotcrete, or any other type of -crete. Because of this utter lack of knowledge and experience, I thoroughly enjoyed my time at this year's National Plasterers Council (NPC) annual conference in New Orleans.

Protect Pool Plaster with LSI Balance from the Start

Pool builders, plaster applicators, and service techs know that a pool startup can be a real pain. Plaster dust is just the tip of the iceberg. For residential pools especially, most pools have water filling them within hours of finishing the plaster. That means the tap water and its chemistry is immensely important in the curing process (hydration) of new pool plaster.

Carbonate Scale: The Hardened Truth

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). Like most of our articles on the Orenda blog, this article is meant to simplify chemistry so that the chemistry can be better understood .
