Think of chlorine like that friend who means well but goes overboard at a party. It does kill the bad stuff—bacteria, algae, the works—but too much of it can turn your backyard oasis into an irritant factory. High chlorine can dry out your skin, turn blonde hair greenish (yes, really), and make your eyes feel like you’ve been chopping onions for an hour.
And let’s not forget the smell. That “pool smell” people complain about? It’s actually from chloramines—a chemical byproduct when chlorine mixes with sweat and sunscreen. So if your pool stinks, it’s not clean; it’s begging for a chill pill.
