Calcium nodules in pools look like little calcium volcanos or blisters that ooze out of pool walls and floors. In this article we cover two opposing viewpoints about what causes calcium nodules, and lay out the facts that everyone agrees on. Then we'll discuss how to prevent and fix calcium nodules.

And no, the calcium you see in the spring time is probably NOT scale. Problems can be prevented by taking an LSI-based approach to pool winterization. In this article we will explain how.
Many people think the Orenda Startup™ is basically a "Calcium Startup". But that's incorrect, and we want to set the record straight. The Orenda Startup™ is an LSI startup.
