Stop Chasing Fine Dirt: Bottom Feeder Cartridge...

The Pool Guy Podcast Show ·

2026/01/12

Dust lines, cloudy steps, and second passes with a manual vac eat time and profit. We tackled the root problem—fine debris slipping through bags—and put the Bottom Feeder Cartridge Assembly Kit 2.0 to the test. The result is a portable vacuum that captures down to about 20 microns without losing thrust, letting us collect leaves and silt in one run while keeping maneuverability in tight spaces like spas and benches. We break down why micron bags hit a wall as they load with dust, forcing wat...

Small Truck: When Going Compact Makes Sense

2026/01/06

The truck you drive can either protect your margin or quietly drain it, and most pros overestimate how much vehicle they really need. We walk through a practical, field-tested approach to choosing a pool service rig that balances chemical safety, daily ergonomics, and total cost of ownership. From compact cars with hitch carriers to mid-size workhorses and full-size comfort machines, we talk through what actually matters when you’re loading chlorine, parking in tight neighborhoods, and making...

2026/01/05

Two truths shape modern pool care: the fundamentals haven’t changed, and expectations never stop rising. We dig into why pool service remains resilient through recessions, how green pools trigger vector control action, and why owners treat upkeep like insurance when a basic build can top $130,000. From chemistry that still works to routines that keep gear alive, we connect the dots between steady craft and smart business. We also unpack the big shifts you’re seeing on the pad.

Balance or Bust: Finding the Ideal pH with Eric Knight

The Pool Guy Podcast Show ·

2026/01/02

Forget the old rule that outdoor pools must live at 7.4 pH. We dig into why cyanuric acid, not pH, is the dominant force behind chlorine strength in the sun, and how reframing your strategy around the FC-to-CYA ratio can reduce algae, cut costs, and protect your surfaces. With insights from industry committee work and modeling, we explain why a 20:1 CYA-to-free chlorine ceiling matters, why 30–50 ppm CYA often hits the sweet spot, and how to choose targets that keep chlorine working without d...

Pool Chemistry Truths: Chlorine, pH & CYA with Eric...

The Pool Guy Podcast Show ·

2026/01/01

Most pool pros have heard it for years: lower the pH to make chlorine stronger. That’s true in non-stabilized water, but once cyanuric acid enters the picture, the rules change. We sit down with Eric Knight to unpack why the FC-to-CYA ratio, not pH, governs chlorine’s effective strength in outdoor pools—and how that insight can save you time, money, and a lot of acid. We break down the chemistry in plain language. You’ll hear how chlorine splits into hypochlorous acid and hypochlorite ion, w...

Clear water without the constant chlorine chase starts with getting the minerals right. We sat down with Fridge Tweer from PoolRx to unpack how proper sizing, clean filters, and smart booster timing keep mineral levels in the sweet spot so chlorine stays low and algae stays gone. From backyard pools to large commercial bodies of water, we walk through the exact steps that improve clarity, reduce chemical costs, and shave time off weekly service. The conversation digs into the real-world vari...

High CYA & High Metals: Fred Schweer’s Fix-It Formula

The Pool Guy Podcast Show ·

2025/12/30

Algae that won’t quit, stains that appear out of nowhere, and chlorine that seems to do less the more you add—if that sounds familiar, you’re not alone. We sat down with Fred Squeer of Pool RX to unpack the chemistry hiding beneath clear water: dissolved metals and high cyanuric acid. Together we map a straightforward plan to reduce chlorine use, prevent algae, and avoid oxidation events that create brown iron spots or purple copper dust. We start with the truth about metals. Well water, agi...

Clear water shouldn’t require a chemistry degree, a mountain of tabs, or weekly emergencies. We sit down with Fred Schweer, VP of Sales at PoolRX, to unpack how a chelated mineral system—copper, silver, and zinc—eliminates algae and frees up chlorine so your pools stay cleaner with less effort and expense. If you’ve battled microalgae, chased phosphate numbers, or watched high CYA slow your sanitizer to a crawl, this conversation reframes your approach with simple, reliable steps. We break d...

Bob Lowry on Surface Cautions Every Pool Pro Should Know

The Pool Guy Podcast Show ·

2025/12/26

Pools don’t fail just from age or weather; they fail when chemistry, circulation, and surface type don’t match. We dig into the real-world differences between vinyl, fiberglass, plaster, and pebble finishes, showing how each material changes your approach to water balance, sanitizer levels, and maintenance. From ground prep that keeps nutgrass from piercing vinyl to the warranty risks of using trichlor tablets with fiberglass, we share the practical moves that help surfaces last and water sta...

2025/12/25

The calm of a backyard pool and the chaos of a hotel deck look similar from the waterline—but they run on different rules. We pull back the curtain on why commercial water turns volatile under heavy bather load, how chlorine gets consumed faster than you can pour it, and what it really takes to keep guests safe and inspectors satisfied. From oxidation priorities to daily logs, this is a candid look at the work behind a compliant, open-for-business pool. We talk through the core chemistry dif...

Fresh plaster only gets one chance to cure right, and most problems start before the first cannonball. We dive straight into the real-world startup decisions that determine whether your pool finishes smooth and stain‑free or inherits permanent issues. With veteran insights from chemical expert Bob Lowry, we compare the big methods—barrel, traditional, and acid—and map clear rules of thumb for when each one makes sense based on source water and surface type. We get practical fast: test the fi...

The Low pH Danger Zone: Bob Lowry Breaks It Down

The Pool Guy Podcast Show ·

2025/12/23

Ever wonder why a pool can look fine one week and show stains, rough plaster, or a failing heater the next? The culprit is often low pH—water that turns aggressive, dissolves metals, and etches surfaces long before the damage is obvious. We walk through how acidic water behaves, where metals come from, and why stains show up only after the water hits its saturation point. We dig into real-world service scenarios: vinyl and fiberglass pools that trend acidic because they lack buffering minera...

Bob Lowry’s Borate Blueprint for a Better Pool

The Pool Guy Podcast Show ·

2025/12/22

Algae pressure, drifting pH, and vanishing chlorine can make pool care feel like a tug of war. We sat down with renowned chemist and educator Bob Lowry to map out a cleaner, calmer path: use borates the right way, match your CYA to your chlorine needs, and stop fighting the water. The conversation cuts through marketing myths to show why boric acid at 50 ppm stabilizes pH and supports sanitizer performance without turning your maintenance plan upside down. We start by reframing borates as a ...

Crystal-clear water means more than fine micron ratings; it means steady flow, low pressure spikes, and a filter you can actually live with. We dive into the real-world reasons cartridge filters outperform DE and sand for most pools, from massive surface area that keeps PSI stable to a simple cleaning routine that skips the gray dust and regulatory headaches of diatomaceous earth. We walk through how pleated media provides 7x the surface area of common DE setups, why that matters for circula...

Ever wonder why a product that makes your job easier somehow never shows up on store shelves? We tackle that head-on with borates: how 50 ppm boric acid helps tame rising pH in saltwater pools, reduces chlorine and acid use, and even cuts down on algaecide. We walk through where to buy it online, how to test it accurately, and why some retailers avoid stocking it despite clear demand. The bigger takeaway: when you meet customers where they are, you win more than a single sale—you win the rela...
