The Pool Envy® Podcast

Jason Davies

The Pool Envy® Podcast goes beyond surface-level swimming pool advice to examine the standards, systems, evidence, and professional judgment behind pool construction, safety, operation, and failure. Hosted by Jason Davies, a licensed swimming pool contractor and independent consultant, the show explores pool code compliance, construction defects, inspections, workmanship, water chemistry, equipment, litigation consulting, and expert-witness issues through real-world observations and practical explanations. Created for pool professionals, homeowners, property owners, attorneys, and anyone who wants to understand not only what happens in a swimming pool—but why—each episode helps listeners ask better questions, recognize meaningful evidence, and distinguish confidence from informed judgment.

    The Pool Isn’t Green Because It’s Hot

    What if your green pool isn’t really a “green pool problem” at all? This week on Pool Envy, we go way past the usual “it’s hot, add more chlorine” advice and into what’s actually happening inside the water. Why can algae show up even when the pool tests like it has chlorine? What role does CYA really play? Why can poor circulation create opportunities for growth? And why does killing algae not necessarily mean you’ve removed what fed it? To make sense of it, we’re taking an unexpected detour into a strange 1970s liminal-space warehouse filled with waterbed mattresses, buzzing fluorescent tubes, leaking containers, and one very questionable quarter-operated machine. Somehow, by the time we leave, phosphates, sequestration, oxidation, circulation, filtration, microbial growth, and nutrient recycling all make a lot more sense. We’ll also talk about why swimming-pool water is not sterile, why microbes are inevitable, how the sourdough-starter analogy explains algae better than most chemistry lectures, why “I have chlorine” may be the beginning of the conversation instead of the end, and why an old filter can become far more involved in the biology of a pool than most homeowners realize. Copper? Phosphates? Dead algae? CYA? Biofilm? Old filter media? Yep. And through all of it, one idea keeps coming back: Contained isn’t removed.Dead isn’t gone.And algae doesn’t need an invitation — it needs an opportunity. If you’ve ever looked at a pool that went green seemingly overnight and thought, “How the hell did that happen?” — this episode is for you. You may never look at your pool water the same way again.  Sometimes the reflection is the least interesting thing happening in the pool.  Pool Envy, LLC | Florida CPC1460695

    The Strange Case of Swimmer’s Calculus: Teeth, Pool Chemistry & LSI

    Can swimming pool water affect your teeth? The answer involves far more than chlorine. In Episode 34 of the Pool Envy® Podcast, we explore the strange case of swimmer’s calculus — and use it to examine the chemistry connecting our teeth, saliva, swimming pool water, and mineral saturation. We begin with the acquired enamel pellicle, the microscopic protein-rich layer that forms on teeth, including proteins such as statherin, histatins, cystatins, lysozyme, and alpha-amylase. From there, we examine dental calculus, calcium-phosphate mineralization, hydroxyapatite, and documented dental erosion among frequent and competitive swimmers. Then we bring the chemistry back to the swimming pool. What happens to carbonate chemistry as pH changes? How are pH, alkalinity, calcium hardness, and mineral saturation connected? Why can calcium carbonate either remain dissolved, precipitate as scale, or become vulnerable to dissolution from calcium-containing pool materials? We use those questions to explore the Langelier Saturation Index (LSI) and an important concept often missed in swimming pool water chemistry: individual test results cannot always be interpreted independently. We also explain an important distinction between dental and swimming pool chemistry. Tooth enamel consists primarily of hydroxyapatite, a calcium-phosphate mineral, while LSI describes saturation with respect to calcium carbonate. They are different mineral systems, but both demonstrate why pH, dissolved minerals, saturation, and the surrounding chemical environment matter. This episode may be especially interesting for dentists, dental hygienists, orthodontists, endodontists, prosthodontists, restorative and biomimetic dentistry professionals, competitive swimmers, aquatic professionals, swimming pool operators, and water chemistry professionals. Clear water tells us what the water looks like. Chemistry tells us what the water is doing. Pool Envy® — Standards, not suggestions.CPC1460695

    The First Question Is Probably Wrong | How to Spot Real Expertise

    How do you choose a pool builder and how can you tell whether someone truly understands the work they are selling? In this episode of The Pool Envy® Podcast, Jason Davies explains why the first question homeowners ask is often the easiest question rather than the most important one. Choosing tile colors, pool finishes, and construction schedules matters—but those choices reveal little about what will keep the finished pool performing years later. Using examples from recent Standards & Systems Evaluations, Jason examines one swimming pool where tiles were already coming loose and another installation where roughly one-quarter of the tile was left spanning unsupported space. The homeowner had been promised the builder would send “our best guy,” but confidence, experience, premium products, and reassuring language are not substitutes for a sound installation method. You’ll learn how to move beyond “trust me,” technical jargon, rehearsed construction sequences, and product-name promises by asking one revealing question: “What site or environmental condition could cause you to change that plan?” Anybody can explain what comes next. A true professional should be able to explain why it comes next, what conditions must be verified, and what would require the plan to change. You didn’t hire only labor. You hired judgment.

    Reputation Over Fame

    In this episode of The Pool Envy® Podcast, Jason Davies discusses the philosophy behind his work as an independent swimming pool consultant, litigation consultant, and expert witness. Rather than focusing on pool repairs or construction techniques, this conversation explores the principles that guide every technical investigation: objectivity, repeatable methodology, professional boundaries, and following the evidence wherever it leads. Why would an expert tell a potential client, "You probably don't want to hire me?" Why does reputation matter more than fame? And why is "I don't know yet" sometimes the most professional answer? Whether evaluating construction defects, documenting safety concerns, comparing observations to applicable standards, or assisting attorneys with technical investigations, Jason explains why an investigator's responsibility is not to advocate for one side—but to remain independent, factual, and objective. Topics discussed include: • Reputation versus recognition in professional practice• The difference between an opinion and a technical investigation• Why methodology matters more than conclusions• Professional boundaries and conflict checks• The role of independent expert witnesses in litigation consulting• Why calm, objectivity, and disciplined thinking produce better investigations Whether you're a homeowner, contractor, attorney, engineer, insurance professional, or another consultant, this episode provides insight into the mindset behind evidence-based investigations and professional integrity. Because your job isn't to judge. Your job is to be truthful. Be factual. Be authentic. Be honest. Ask questions. Document carefully. Remain objective. Remain professional. And above all... Remain in control. Pool Envy, LLC | Florida CPC1460695
