Why Dog Pools Are Never “Balanced” 16.01.2026 17:40
Clients adore their dogs, and many let them swim daily. We get real about what that means for your route: higher bather load, stubborn scum lines, clogged filters, and chlorine that seems to vanish overnight. Instead of fighting the habit, we show you how to build a resilient service plan that keeps water safe, controls algae pressure, and protects your margins without overpromising on crystal cla...

Want a pool service schedule that actually lets you take time off without losing momentum or money? We break down a practical framework for solo operators and small teams to reclaim rest, reduce burnout, and keep customers happy year-round. We start with the hard truth: summer time off is risky. Heat, bather load, and algae pressure make July and August the most fragile weeks on a route. Then we f...

Small Truck: When Going Compact Makes Sense 06.01.2026 20:50
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 throu...
Dive In: Season 10 Starts Now 05.01.2026 19:27
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...
Balance or Bust: Finding the Ideal pH with Eric Knight 02.01.2026 14:51
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...
Pool Chemistry Truths: Chlorine, pH & CYA with Eric Knight 01.01.2026 23:49
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 i...

From backyard pools to large commercial bodies of water, we walk through the exact steps that improve clarity, reduce c...
High CYA & High Metals: Fred Schweer’s Fix-It Formula 30.12.2025 18:30
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 crea...
Fred Schweer: The Science Behind PoolRx+ and Cleaner Water 29.12.2025 21:07
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 saniti...
Bob Lowry on Surface Cautions Every Pool Pro Should Know 26.12.2025 19:58

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 tri...
Commercial vs Residential: Bob Lowry Explains the Big Differences 25.12.2025 22:10
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 loo...

The Low pH Danger Zone: Bob Lowry Breaks It Down 23.12.2025 19:34
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 se...
Bob Lowry’s Borate Blueprint for a Better Pool 22.12.2025 22:06
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 pe...
The Clear Choice: How Cartridge Filters Outshine Sand & DE 19.12.2025 18:54
Crystal-clear water means more than fine micron ratings; it means steady flow, low pressure spikes, and a filter you can actually live with.
