If you’ve got a spa or a high-end pool, you might have a UV light or ozone generator. These gadgets basically bully combined chlorine into submission using light or gas. They’re the bouncers of the water world. Once installed, they keep working 24/7 to prevent combined chlorine from even showing up.
But here’s the kicker: They don’t completely replace shocking. Think of them as your regular gym sessions—you still need to do the occasional heavy lift. Use them to reduce your shock frequency, not to skip it entirely. And if your spa smells like a photocopier, that’s ozone, not chlorine. Good news: it’s harmless and it means the system is working!
