Anyone using ozone or UV stuff in their pool?

Been hearing about these systems for a while now, but never really knew if they’re worth getting. I mean, I get the idea, less chlorine, “cleaner” water or whatever, but is it that much better?

Or is it one of those things that sounds cool but you still end up doing the same work anyway? It would be great to hear from someone who’s used one, not just what the brochures say. been using chlorine for years, and it works. Just curious if there’s a better way that’s not a pain to maintain.
 
I’ve had ozone and UV running together for about two seasons now. They definitely help water feels “softer,” less of that strong chlorine smell, and I don’t get as much eye irritation. But it’s not magic. You still need chlorine, just not as much. I’d say maintenance is about the same, maybe a little less shocking overall. So yeah, it’s better, but not a total game-changer if you’re already dialed in with chlorine.
 
I went the UV-only route and honestly... it’s nice, but not life-changing. The water does stay clearer longer, and I’ve had fewer issues with algae and cloudiness. But it didn’t replace any work I still vacuum, test, and balance weekly. It’s more of a support system than a shortcut. If your chlorine routine works, UV just adds a little polish to it. Worth it if you're a pool nerd like me, maybe not if you're hoping for a hands-off miracle.
 
I tried ozone for the first time last year, kind of just wanted to see what all the fuss was about. One thing I noticed that surprised me: the pool smell changed. Not the usual bleachy vibe, just... cleaner? Hard to describe.

But yeah, it doesn’t eliminate chlorine. I still do it, just not as much. One unexpected thing was the installation; mine needed a bit more plumbing adjustment than I planned for. Nothing crazy, just a heads-up if you go that route.

I wouldn’t say it cuts your work in half or anything, but the water does seem to bounce back quicker after heavy use or storms. So for me, it’s been a nice bonus, just not a full-on replacement.
 
I’ve been using a UV system for a year now. It doesn’t replace chlorine, but I’ve noticed I don’t need to use as much, and the water feels cleaner. Maintenance hasn’t really changed, but I like the added peace of mind.
 
I’ve been running a UV system for a year along with my usual chlorine routine. Honestly, it’s made a noticeable difference in how the water feels, much clearer, less of that harsh chlorine smell, and my eyes don’t sting as much. That said, it doesn’t replace chlorine at all. I still keep a baseline level in the pool, but I’m adding less than I used to.

The tricky part I didn’t expect was the pump timing. If the water doesn’t circulate through the UV unit enough, it doesn’t do much. Once I adjusted that, the water seemed to bounce back faster after a weekend with heavy swimming, and I didn’t have to shock as often.

It’s not a magic solution, but for me, it’s made pool maintenance easier and the water nicer to swim in. I’d say it’s worth it if you’re looking for cleaner water without completely changing your routine.
 
I’ve been experimenting with a mix of UV and ozone for the past few months, and while it’s not a complete game-changer, I’ve definitely noticed a difference. The water’s clearer, and I use less chlorine, but I still find myself testing and balancing regularly. For me, it’s been a smoother and quieter way of handling maintenance, even though it's not a miracle fix!
 
I actually held off on adding one of these systems for years because I figured it was just another gadget. Finally tried UV last season, and what stood out most to me wasn’t less work, but less guessing. The water seems to stay more stable between tests, so I’m not chasing numbers as often. Chlorine use is still part of the deal, but I don’t feel like I’m dumping it in constantly.

One small downside people don’t talk about much is cost vs. payoff. The upfront install isn’t cheap, and if you’re already good at keeping chlorine balanced, the benefit might not feel huge. For me, the payoff was more comfort and consistency rather than “less maintenance.” So I’d say it’s not hype, but it’s also not a magic bullet.
 
I looked into these a lot before deciding, and what I kept hearing (and now seeing myself) is that they’re more of a supplement than a replacement. I went with ozone, and while it didn’t cut my chlorine use in half like I hoped, the water does stay clearer and seems to handle heavy swim weekends better. One thing I didn’t expect was how much more consistent my chlorine levels stayed week to week. So yeah, still some work involved, but I’d say it smooths out the ups and downs if you don’t mind the upfront cost.
 
I ended up adding a UV unit earlier this summer, mainly because I was curious if it would actually make a difference. What I’ve found so far is the water feels “fresher,” and I’m definitely using a bit less chlorine than before. The biggest change for me is after a busy weekend when a lot of people swim, the water seems to clear up faster without needing a big shock treatment.

That said, it hasn’t replaced chlorine at all. I still keep a baseline level in the pool, and the regular testing/balancing routine hasn’t gone away. It’s more of a helper than a replacement. One thing to watch is your pump schedule; the UV only works when the water’s moving, so I had to adjust run times to get the full benefit.

So is it worth it? I’d say yes if you’re looking for clearer water and less chemical smell, but no if you’re hoping it’ll eliminate all the usual pool chores.
 
I’ve been using a UV system alongside my normal chlorine routine for several months now. The water feels smoother, stays clearer longer, and the chlorine smell is noticeably lighter. It doesn’t replace chlorine, you still need a baseline but it reduces how much you have to add and helps the pool bounce back faster after heavy use. The main thing to get right is pump timing; the UV only works when water flows through it. Overall, it’s a helpful supplement, not a magic fix, but it makes maintenance easier and the water more pleasant.
 
I was pretty skeptical at first too, mostly because chlorine has always “worked” for me. After running a UV unit for a while though, I’d say the real value isn’t that it replaces anything, it’s that it changes how forgiving the pool is.

One thing I didn’t see mentioned much before installing was sizing and placement. If the unit is undersized for your pool or installed where flow is inconsistent, you won’t notice much at all. A friend of mine thought his UV was pointless until he realized it was barely seeing enough flow during normal pump cycles. Once that was sorted, the difference was a lot more obvious.

Another factor is longevity and upkeep. UV bulbs don’t last forever, and ozone components eventually wear out. It’s not hard maintenance, but it is another thing on the checklist once a year or two. If you’re the kind of owner who hates extra parts and reminders, that’s worth considering.

So is it better? Yeah, in the sense that the water behaves better and recovers faster when something throws it off. Is it less work overall? Not dramatically. It’s more like the pool becomes less temperamental. If you enjoy dialing things in and want a smoother experience, it’s a nice upgrade. If you’re happy with chlorine and don’t mind staying on top of it, you’re not missing out on a miracle.
 
If you and I are being honest, UV usually feels “better” not because it removes the work, but because it can reduce chloramines so smell and irritation drop, while the main work stays the same, you still keep FC matched to CYA, manage pH, and run good filtration, so if your pool is already stable and you’re happy, UV isn’t necessary, but if you deal with chlorine smell, stinging eyes, or heavy bather load, UV can be a noticeable upgrade without adding much maintenance.
