Mine was a slow-burn disaster rather than an instant one. I went away for a long weekend thinking everything was set perfectly. Came back to water that looked okay at first glance, but the steps and corners felt slick. Turns out the pump timer failed on day one and the pool basically sat still in summer heat for three days.
What made it worse was that I kept adding chlorine thinking it would “catch up,” not realizing circulation was the real issue. Ended up with cloudy water, clogged filter, and a chemistry mess that took way longer to fix than it should’ve. Lesson learned the hard way: moving water matters just as much as chemicals, and timers are not something to blindly trust.
Pool ownership definitely teaches patience… and paranoia.
