Pool Chemistry and Maintenance From a CPO

October, 7 a.m., a 48-unit Scottsdale HOA community poolside. Three sycamores towered over the deck, their branches shedding leaves with industrial efficiency. I’d cleared the skimmer basket before sunrise. By 9:30, the pump was cavitating hard. Four service calls later — noon hadn’t even arrived — homeowners were already lighting up my phone. You’ve been … Read more

Two competing pieces of advice circulate constantly around pool decks and online forums, and they directly contradict each other. One says “pH drops naturally over time, so you shouldn’t add acid unless it gets above 8.0.” The other insists “high alkalinity causes everything, lower it first and pH will follow.” One of these is wrong … Read more

Back in spring, I’d arrive at one of my HOA pool properties to witness the identical scene unfolding: a brilliantly clear pool surface completely blanketed under a thick coating of yellow pine pollen, accompanied by a homeowner gripping a skimmer net with the expression of someone who’d personally declared war on the local tree canopy. … Read more

A call came through one Tuesday morning from a property manager in Tempe: “The water looks fine, but the bottom feels gritty. My guy says we don’t need to vacuum because the filter’s running 24/7.” I drove out that afternoon. The pool floor was carpeted in a half-inch layer of silt, algae spores, and decomposed … Read more

What happens when a single safety measure fails? That’s the question that stopped haunting me the moment I learned to think in systems instead of checkboxes. Years back, a Scottsdale HOA woke up to a four-year-old on the pool deck at dawn—the child had found a weak gate latch, slipped through before anyone could stop … Read more

No product manual spells this out, and the guy behind the counter at your pool supply won’t mention it either: the cleaner type you buy determines whether your pump stays healthy, your filter lasts a full season, and whether fine sediment actually leaves the water or just circulates through your system indefinitely. I discovered this … Read more

Skipping a vacuum step in above-ground pool maintenance leads to algae blooms faster than you’d expect — and once spores take hold in that confined water volume, chemistry alone won’t save you. During my years overseeing resort and municipal facilities across Arizona and Nevada, I watched pools deteriorate in 48 hours flat when sediment settled … Read more

A $1,200 mesh pool fence and a $2,800 mesh pool fence landed on the same property once—both installed within six months of each other by different homeowners in my service area. The budget system held up for four seasons before mesh sag became noticeable enough that the gate wouldn’t close smoothly. The premium system is … Read more

Stand poolside on a hot afternoon and look at the deck around the waterline. Notice the dust settling on the concrete, the way the sun glints off bare sleeves where poles might sit. Now imagine that same space transformed by a removable mesh barrier — one that wasn’t there yesterday, one you’ll take down next … Read more

Over my fifteen-plus-year career managing aquatic facilities across the Southwest — from resort complexes to municipal centers to residential HOA communities — the distress call that lands most often in my inbox follows the same script: “Nadia, I shocked the pool last night the way I always do, and by morning the entire floor and … Read more
