Pool Chemistry and Maintenance From a Backyard Pool Owner
Nadia Caldwell · July 15, 2026
I’ve helped with pools across Arizona and Nevada, and I can tell you the number-one question I get from vinyl liner pool owners in the spring is: “Can I add a sun shelf to my pool like the one at the resort down the road?” The honest answer? It depends — and the “depends” part … Read more

Not long ago, a friend of a friend with a backyard pool asked me whether her salt cell was defective. She’d replaced it three times in two years. “Nadia,” she said, “is this thing broken, or am I doing something wrong?” We went through her maintenance routine, tested her water, and—surprise—the cell wasn’t actually dead. … Read more

It’s July in Scottsdale. You went to bed last night with a crystal-clear pool, and you woke up to what looks like a swamp. I’ve been there—actually, I’ve seen enough pools around the Southwest to tell you that this scenario plays out almost weekly during monsoon season. The worst part? That panic moment when you … Read more

You’ve probably encountered two conflicting pieces of advice online or heard them poolside: “Just buy a suction cleaner, they’re cheap and easy,” versus “Suction cleaners will destroy your filter in one season if you have trees.” One of those statements is misleading, and the other misses crucial context. The truth sits in the middle — … Read more

A neighbor called me in a panic last summer after their pool had been shocked three separate times within fourteen days. They’d scrubbed surfaces, run extended backwash cycles, and introduced algaecide in quantities that seemed excessive even for a serious bloom. The greenish cast remained stubbornly present. Recognizing this pattern? When your algae treatment efforts … Read more

The phone rings in July, and it’s always the same story: “My above-ground pool turned green overnight, and I swear I’m doing everything the manual says.” I ask a few questions about their routine, and the culprit emerges almost immediately — they’ve lifted their maintenance strategy straight from in-ground pool playbooks. That approach fails spectacularly … Read more

What’s actually stopping your pool from clearing up when algae blooms hit? Odds are strong it’s not your chlorine dose — it’s the brush you’re holding. Picture this instead: it’s dawn on a Tuesday at a big 75,000-gallon pool outside Phoenix, and the shallow end’s concrete steps have developed a yellowish-green film thick enough to … Read more

Safety devices manufactured by pool companies don’t come with the context you actually need. Neither does the store clerk restocking inventory. What nobody tells you upfront is that a removable mesh fence is only as effective as the habits of the people around it — and that one moment of negligence, one unlatched gate, can … Read more

Your pool’s eye-stinging reputation may have nothing to do with excess chlorine—and everything to do with chemistry you’re not actually measuring. Back in the middle of a Scottsdale summer, I helped a neighbour with a pool that had been causing irritation for days. The numbers they had were 3.0 ppm total chlorine, which looked like … Read more

A neighbour called me in a full panic last summer. Her 25,000-gallon pool had turned into something resembling swamp water between sunset and sunrise, and the family was expecting people over at noon. I asked three straightforward diagnostic questions, pinpointed the issue in under 120 seconds, and walked her through a complete fix that same … Read more
