As pool owners, we’ve all wondered at some point – what happens if pH is too low? I remember the first summer after we installed our pool, when I was still learning the ropes of water chemistry.
The pH dropped lower than it should a few times, but I didn’t think much of it. The water seemed clear enough and my family was happily swimming away.
Boy, was I naive about the effects of low pH back then.
That winter when opening up the pool, I discovered small holes forming in the plaster finish and the metal ladder was showing some faint corrosion. The pool guy I hired took one look at my chem log and shook his head. “Your pH has been way too low,” he said. “You’re gonna start seeing some real damage if you don’t get that under control.”
Turns out acidic water literally eats away at pool surfaces and equipment. And there’s more – it clouds up easily, irritates skin and eyes, and causes a whole cascade of chemical issues in the pool. Not fun for swimmers or my wallet trying to make repairs!
So what exactly does happen when pH creeps too far below the recommended levels between 7.2-7.8? The impact of acidic pool water on both equipment and health ended up being a harsh lesson for me to learn. Let me break down what low pH can do so you don’t make the same mistakes I did…
