Spas, Splash pads, and Waterpark rides... Why Aeration Causes pH Rise in Swimming Pools Ever wonder why the pH in certain pools always seems to run high, no matter how…

Talking Pools Podcast

If you’ve ever stared at a test kit like it personally insulted your family… welcome home.

Talking Pools Podcast is the pool industry’s “pull up a chair” show—part shop talk, part field manual, part therapy session—built for people who actually live on pool decks: commercial operators, service techs, builders, facility managers, and anyone responsible for water that can’t afford to go sideways. The network was created to level up the pool industry with real-world conversations on water chemistry, filtration, troubleshooting, construction, safety, and the business side of keeping pools open and budgets intact.

Here’s the hook: it’s not theory-first. It’s experience-first—a roster of seasoned pros (with 250+ years of combined “been there, fixed that” wisdom) turning complicated problems into practical moves you can use the same day. And it’s not one voice, one vibe, one corner of the industry: it’s a network of shows designed to reflect how diverse this work really is—different regions, different specialties, different personalities.

Also worth saying out loud: women aren’t “special guests” here—they’re on the mic as hosts, from the beginning, with an intentionally balanced roster. That matters, because the best ideas in this industry don’t come from one lane—they come from the whole road.

If you want a podcast that can make you laugh and make you better at what you do—without pretending the job is easier than it is—Talking Pools is the one you queue up before the first stop, and keep on when the day starts getting weird.

Ask a question here

Your total alkalinity is 100 ppm. So is the pool next door’s. Why does one keep climbing in pH while the other takes a dive when you add alum?

On this Floc-It Friday, Rudy Stankowitz breaks down what’s behind that number on your test kit. He runs through a pool with 100 ppm total alkalinity and 100 ppm cyanuric acid, shows how the one-third shortcut changes the Langelier Saturation Index (LSI) calculation, and explains where that shortcut can get you in trouble. Then he takes it back to the equipment pad with a pool whose pH keeps creeping up, an acid dose, and an alum treatment.

Rudy opens with a thank-you to Olga Welch at Rutgers University for a letter about his years teaching pool water quality. He also reads past the headline on Haviland’s announced $26 million Indiana facility and gets to the questions that matter when chemicals are included in your monthly service rate. Will it handle the products you buy? Will it change what’s available? What will you actually pay?

And in Hudson, Florida, two pickups roll onto a jobsite with a championship belt for John Poma, the 2026 Talking Pools Podcast Pool Industry Mentor of the Year. Rudy tells the story of the surprise and shares how John handles a late-night call about a plaster problem. He asks what you saw, what you checked, and what you think it means. The next time you see it, you know where to start.
