Ever run your hand across pool coping and feel sandpaper? That texture tells a story about water that’s either starving for calcium or dumping it everywhere. We take you inside the Langelier Saturation Index—the tool that predicts whether your water will corrode metal and etch plaster or lay down crunchy scale on tile, heaters, and salt cells—and show you how to control it with confidence. We start by anchoring the basics: calcium hardness sets the foundation, temperature shifts the baseline...
Fighting red eyes, cloudy water, or scale that keeps coming back? We unpack the exact chemistry that drives pool comfort and clarity, then give you a simple plan to control pH without wrecking alkalinity. You’ll learn why total alkalinity is the true pH buffer, how cyanuric acid and borates play supporting roles, and when to pick borax, baking soda, or muriatic acid to get fast, stable results. We start with the essentials: what pH means for swimmer comfort, equipment protection, and chlorin...
Your pool isn’t misbehaving—your targets are. We take you past vague “ideal ranges” and into precise numbers that keep water clear, equipment protected, and algae out for good. Starting with the seven essentials—pH, total alkalinity, calcium hardness, temperature, TDS, cyanuric acid, and measured chlorine—we explain how each parameter supports the others and how to prevent scale or corrosion using the Langelier Saturation Index. You’ll hear why a steady pH of 7.5 and TA near 90 ppm form a sta...
Sunlight, strength, and shelf life decide whether your chlorine dollars deliver crystal water or fade by Friday. We unpack the real-world playbook for using liquid chlorine (sodium hypochlorite) as a primary sanitizer—what it is, how strong it should be, and why pairing it with the right stabilizer keeps free chlorine steady all week. We start by clarifying the difference between commercial-grade liquid chlorine at 10 to 12.5 percent and household bleach at 5 to 8.25 percent. Then we get pra...
Tired of pool rules that don’t add up? We peel back the layers on the industry’s most persistent myths and replace them with chemistry you can trust. From the “acid column” idea to the belief that liquid chlorine always drives pH sky high, we show where the logic sounds right and why the science says otherwise. You’ll learn how acid truly mixes on contact, why slugging can scar plaster and vinyl, and how to dose safely using circulation to your advantage. We also tackle the big one: “chlorin...
Chlorine keeps vanishing, the water looks fine, and your test kit keeps gaslighting you. We’ve all been there, and the fix isn’t “just add more.” I walk through the real reasons a chlorine pool refuses to hold a residual and the exact order to solve them: restore flow, clear the water, set cyanuric acid in the sweet spot, and only then fine-tune sanitizer. You’ll hear why torn DE grids, clogged cartridges, and starved runtime quietly turn your pool into a chlorine sink — and how a simple filt...
Chlorine at zero and a control panel full of mixed messages can make any pool owner or service pro feel stuck. We break the problem apart step by step so you can restore steady saltwater chlorination with confidence, starting with the most common culprits and moving into the hidden faults that waste time and chemicals. We start at the cell, explaining how thin scale films quietly choke production long before a “clean cell” warning appears, and the right acid‑wash ratios that protect plates. ...
Tired of chasing the “perfect” pool water tester that does it all? We unpack the trade-offs behind the most trusted tools on a pro’s truck and show how to build a smarter testing system that saves time, reduces cost, and delivers accurate, defensible results. First, we put the Lamotte SpinTouch under the microscope. It’s blazing fast and highly accurate across a wide panel of factors, making it ideal for commercial pools, startups, and tough problem jobs. We talk candidly about the price of ...
Algae looks small, but it’s a budget killer. We pull back the curtain on how blooms steal minutes, erode customer trust, and rack up chemical costs across a route—and then we share a prevention playbook that keeps water clear and margins strong. From the real science behind sanitizer strength to practical field tactics, this episode is built to save you time and money while earning client confidence. We start with the problem behind the problem: why algae shows up even when your free chlorin...
What if your “quick shock” could bleach a liner, stain a step, or even trigger an explosive reaction in your feeder? We take a hard, practical look at calcium hypochlorite—cal hypo—and share how pros use it for powerful oxidation without piling on cyanuric acid. From real-world dosing to regional water chemistry, we map the choices that keep your pool clean and your surfaces safe. We start with clarity on strength: why 73 to 78 percent cal hypo nearly matches a gallon of 12.5 percent liquid ...
Big bather load on the calendar and worried about cloudy water, itchy eyes, or a long recovery the next day? We brought in legendary chemist and educator Bob Lowry to map out a clean, simple plan that keeps your water clear and your sanity intact. We start with the pre-party checklist: raise free chlorine a few ppm, add a measured dose of non-chlorine oxidizer, and keep the pump and filter running. Then comes the sleeper tactic that saves the most money and headache—pre-swim rinsing. B...
Think evaporation lowers cyanuric acid? Think again. We open the cover on persistent pool myths with help from the late Bob Lowry’s clear, data-driven explanations, and show how small assumptions can create big chemistry problems over a season. First, we break down why CYA never leaves with evaporation—only pure water does. That means every trichlor tablet quietly stacks CYA week after week, often hitting 100 to 150 ppm in a single swimming season. We compare sanitizer byproducts in plain te...
A black stain appears the moment cal hypo hits the floor—panic sets in. We unpack why that stain isn’t a new disaster but copper changing form, and how to turn a scary moment into a clean, controlled fix. With guidance from Bob Lowry, we break down the chemistry that matters, the tools that actually remove metals, and the habits that keep stains from returning. We start with the copper story: how copper sulfate hides in plain sight until oxidation turns it into black copper oxide, and why as...
The way we treat pool water is changing fast, and for good reason. Drought cycles, shrinking reservoirs, and tighter local rules are pushing the industry to prove it can deliver joy and safety while using far less water. We brought water expert Terry Arko back to chart a practical, field-tested path: smarter filtration, measured backwashing, proactive partial drains, and chemistry that prevents waste before it starts. We start with the history many of us lived through—hosing decks, routine b...
The best pool chemistry advice is the kind you can use on your next route. We sit down with Terry Arco to share how Bob Lowry’s teachings are being refined into fast, field-ready training for residential service pros, plus a major update to the IPSA manuals that shaped a generation of technicians. If you’ve ever held chlorine at 3 ppm and still fought algae, or watched CYA granules sit on the floor in cold water, this walkthrough connects the dots between LSI, stabilizer, and free chlorine in...
Ready to make 2026 the year your route runs smoother, faster, and with less strain? We’re sharing the exact tools that pay you back in minutes saved and backs spared, plus how to pick the right version for your truck, your clients, and your local conditions. We start with the true workhorse: your pole. Carbon fiber has become the smartest upgrade for daily service thanks to its lighter weight, stiffness, and durability. You’ll hear how Primate’s vertical lever locks and 3-piece reach let you...
Ready to land commercial pool accounts without racing to the bottom on price? We break down exactly how to win bids with HOAs, apartments, and hotels while protecting your margins, your time, and your sanity. From first contact to long-term retention, this is a step-by-step guide to building a profitable commercial line that doesn’t drain your residential route. We start with how decision-making works behind the scenes: HOAs need multiple bids, boards are volunteer-led, and property managers...
Confusion is expensive. We walk through the simple service agreements and targeted waivers that keep your pool business protected when jobs get messy, from green pool rescues to acid washes that carry real surface risk. Instead of relying on verbal promises, we show how a one-page agreement sets clear expectations, defines what’s included, and outlines billing, weather exemptions, and vacation pauses so surprises don’t turn into cancellations or chargebacks. Green pools are a mystery until t...
Ever had a client say, “If it’s not broken, don’t fix it,” while you stare at a rusted filter and a pump on life support? We’ve been there. This episode breaks down the real-world tactics we use to manage budget-conscious pool owners without sacrificing water quality, service standards, or our sanity. From aging equipment that “still runs” to two-hour runtimes in peak summer, we unpack where to accommodate and where to draw a hard line. We start with the classic dilemmas: old pumps, rebuild-...
Your route doesn’t have to be a grind. We unpack the simple habits that separate smooth, profitable days from chaotic ones, drawing on three decades of pool service experience to show how routine, timing, and smart planning eliminate headaches before they start. The heartbeat of the conversation is a reliable workflow: show up the same day and roughly the same time each week, then run the same sequence at every stop so nothing gets missed. We explain why dosing chemicals last prevents second-...
