The Pools Scientific Podcast

There is one calculation that determines whether your pool water is slowly destroying your equipment, etching your plaster, or quietly depositing scale on every surface it touches. Most pool owners have never heard of it. Most pool guys never mention it. It runs in the background of every service visit I do, every single week. Today we talk about the Langelier Saturation Index. What it is, what it measures, and why getting it wrong is the most expensive mistake in pool ownership that nobody sees coming.Show notes and free resources at PoolsScientific.com.

Your test strip shows chlorine. The water looks clear. But is your chlorine actually working?In this episode, chemical and nuclear engineer John Cooper breaks down the relationship between cyanuric acid (CYA) and free chlorine — and the single ratio that determines whether your sanitizer is doing its job. It's called the 7.5% Rule, and most pool owners have never heard of it.John covers what CYA is, why it belongs in your pool, how it quietly blunts your chlorine's effectiveness as it accumulates, and what to do about it. You'll leave with a specific free chlorine target calculated for your actual pool — not the generic number on the label.Show notes and the full CYA-to-FC reference table: PoolsScientific.comSubscribe for new episodes every Tuesday.Show notes and free resources at PoolsScientific.com.

John got a call from another pool guy who was in way over his head. What he found when he walked into that equipment room is the single best argument for why pool care needs to be treated as a science — not a trade skill passed down by feel and guesswork. This is the episode that explains why Pools Scientific exists, what’s fundamentally broken about the way pool care is practiced, and what it actually costs when the science gets ignored.
