Bob Lowry Meets Ben’s Best Guess Chart: Pool Chemistry Unlocked

In this episode, I’m unpacking one of the most important—and misunderstood—relationships in pool chemistry: free chlorine (FC) and cyanuric acid (CYA). Using Ben’s Best Guess Chart as a foundation, and layering in insights from Bob Lowry, I’ll explain how to find the sweet spot for chlorine levels so your pool stays safe and algae-free. This is pool chemistry demystified, and once you get it, your pool care will never be the same.
