Pool Chemistry and Maintenance From a Backyard Pool Owner

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. Over years of poking around pools across Arizona and Nevada, I watched pools deteriorate in 48 hours flat when sediment settled and decomposed … 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 fifteen-plus years of chasing pool chemistry around the Southwest — 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 walls are covered in these awful brown and green stains. I’ve … Read more

Dose 20 ppm of calcium hypochlorite shock at a CYA level of 50 ppm, and you’re managing chemistry. Install a gate that doesn’t self-latch, and you’re gambling with a child’s life. Over the past fifteen years I’ve chased water chemistry on my own pool and plenty of others. It boils down to variations on this … Read more

Around this time each year, I field a familiar type of call from someone who installed an above-ground pool during the previous warm months. The message is usually some variation of “I was told this would be straightforward” and concludes with me walking them through a murky-brown water emergency, a liner that appears aged beyond … Read more

A 500-watt draw on a circuit that should only handle intermittent underwater loads—that’s what I see when I test the existing setup at pools I take over, and it never stops bothering me. The fixture sits submerged in your backyard, running on the same voltage as your kitchen counter, surrounded by children on summer evenings. … Read more
