Episode 29: Pool Maintenance Myths: How Old Habits Damage Your Pool | The Pools Scientific Podcast
Pool maintenance myths don't sound like myths. They sound like settled knowledge, because they've been repeated a thousand times. Repeated advice still isn't tested advice. A listener closed an in ground vinyl pool in the mid Atlantic, balanced it to a slightly positive LSI calculated at 40°F (4°C), and asked how to add chemicals under the cover, with no circulation, if the water drifted over the winter. The most common answer was don't. John takes the four ideas behind that answer one at a ...

Episode 28: What Else Could Possibly Go Wrong in Your Pool in Winter? Crystals, Ice, and Other Winter Surprises | The Pools Scientific Podcast
Winter is hard on a pool, and not all of it is explained. This episode sorts what can go wrong under the cover into three piles: Known, Theory, and Shrug. John Cooper starts with the calcium crystals that appear on some plaster pools in spring and gives both published explanations a fair hearing, from Orenda Technologies and onBalance. Then winter dust, gypsum, the odd formations on drain covers, and one pool that opened with a layer of white dust and a pH of 9.2. Then the damage that is comp...

Episode 27: Hot Tub Chemistry: Bromine vs Chlorine and Why Your Hot Tub Isn’t Just a Small Pool | The Pools Scientific Podcast
Your hot tub is not a small pool, and treating it like one is where most of the trouble starts. In this episode, John walks through why a tub is a different animal: more bathers per gallon, water held at 104 degrees Fahrenheit (40 degrees Celsius), and nowhere for anything to go. We cover bromine vs chlorine and how to choose, why dichlor, the jar most pool stores hand you for a spa, quietly builds cyanuric acid until the sanitizer stops doing its job, and what the CDC says about ...

Episode 26: Winter Pool Maintenance: What the Water Does to Your Pool Under the Cover | The Pools Scientific Podcast
Winter pool maintenance is where most pool damage starts, and almost nobody does it. Once the cover goes on, the water sits against the plaster, gelcoat, or vinyl liner for about six months, and cold water changes the chemistry in ways the summer rules don’t cover. John walks through what happens under the cover, why winter pool chemistry runs on the LSI instead of the in season numbers, and what a pool closing kit leaves out. You’ll hear what causes plaster etching in winte...

Episode 25: Pool Plaster Mottling: Causes, Chemistry, and the Real Fix |The Pools Scientific Podcast
Pool plaster mottling is one of the most common complaints in new pool construction, and the industry's standard explanation, installer error or bad water chemistry, is usually wrong. The real cause is calcium hydroxide migration during cement cure, and it has been a solved problem in commercial concrete construction since the 1950s. The pool industry just never picked it up. This episode covers the full mechanism: how Portland cement produces calcium hydroxide as a hydration byproduct,...

Episode 24: The Four-Year Lie — What Your Plaster Is Trying to Tell You | The Pools Scientific Podcast
Pool plaster mottling gets blamed on your water chemistry almost every time. This episode asks a different question. What if the uneven gray discoloration was decided before the pool ever held a drop of water? We get into the science of new pool plaster problems, and what pool plaster warranty coverage actually protects you from, and what it does not. If your plaster is showing discoloration and mottling in the first few years, you are going to want to hear this one before y...

Episode 23: Metal Staining and the Ecosystem of Metals in Pool Water | The Pools Scientific Podcast
Pool metal stains rarely come from just one source, and this episode walks through the real chemistry behind them. John covers where metals and minerals actually enter pool water, why iron, manganese, and copper stain differently, and why calcium and magnesium follow the same solubility rules everyone assumes are unique to metals. He breaks down the difference between a sequestrant and a chelator, walks through a rare copper cyanurate case that took fifteen drain and refill cycles...

Bonus Episode 3: Closing and Winterizing Your Pool | The Pools Scientific Podcast
Closing day is the last time anyone touches your pool's chemistry until spring, and most closing checklists skip the one thing that actually matters: what happens to that water for the next five months. This episode covers pool closing chemistry by pool type, since winterizing an above ground pool, winterizing an inground pool, vinyl liner pool winterizing, fiberglass pool closing, and plaster pool winterizing each carry a different physical risk, not just a different checklist. F...
