Anyone switched to UV or ozone systems instead of just chlorine?

[Mark Davis]

I have been reading about advanced sanitization like UV and ozone systems that help cut down on chlorine use and keep the water cleaner. Has anyone here installed one? Curious if it made a big difference in water clarity or maintenance. Wondering if it is worth the upfront cost.

 

[John Miller]

We added a UV system last season and honestly I noticed the water feels cleaner and there is way less chlorine smell. It does not replace chlorine completely but it definitely helps keep things balanced and cuts down on how much sanitizer we use. Maintenance is still needed but the water feels nicer overall.

I went with ozone a couple of years ago and it made a huge difference for us. The water stays clearer longer and it handled algae a lot better. Still need some chlorine but way less than before. The install cost was a bit steep but worth it for the easier upkeep.

I switched over to an ozone setup about a year ago, kind of as an experiment. Wasn’t expecting much, honestly, but I’ve been pretty impressed. One thing I noticed that no one mentioned, the water feels like it stays “settled” longer between cleanings. Like, less gunk floating around after a busy swim day.

I still use chlorine, just a smaller amount to maintain a base level. The ozone handles more than I thought it would, especially after heavy rain when my old setup would usually go a bit cloudy. The upfront cost did sting a bit, but I’ve been spending less on shock and other chemicals overall, so it’s slowly balancing out.

Would I do it again? Yeah, I think so, just don’t go in expecting to ditch chlorine entirely. It’s more like giving your system a reliable sidekick.

Yeah, I tried an ozone system last year and honestly, it’s kind of a game-changer. The water stays way clearer than before, and algae doesn’t take over as quickly. I still keep a little chlorine around, mostly just for safety, but I’m adding way less than I used to.

One thing I noticed is that the water just “settles” better. After a weekend with a lot of swimmers, it doesn’t get that cloudy, gross look like it used to. I had to play around with the pump timing a bit so the ozone circulates enough; otherwise, it doesn’t do much.

Upfront cost was a bit annoying, I won’t lie, but over time, I’m buying fewer chemicals, and it’s less work overall. Would I do it again? Definitely. Just don’t expect to completely ditch chlorine; it’s more like giving your pool a little backup.

I’ve been using an ozone system for a few months now, and honestly, it’s made a noticeable difference. The water’s clearer, and it feels like the chlorine is working more efficiently. I still use chlorine, but the ozone really helps to keep things in balance. The best part? I don’t have to adjust the levels as often, which is a huge plus for me. It’s not a magic solution, but it sure does make life easier!

I haven’t made the switch myself yet, but I’ve been testing the waters (no pun intended) by helping a friend who runs a UV + chlorine combo. The thing that stood out to me wasn’t just water clarity, it was how much less “work” the chlorine seemed to have to do. The pool held steady longer after storms or heavy use, where mine usually drifts off balance.

One thing worth mentioning though: these systems don’t solve everything. You’ll still need to test and dose chlorine, but it does seem to smooth out the big swings. From what I’ve seen, if you’re already good with regular maintenance, the upgrade just makes the whole process a bit more forgiving.

If budget allows, I’d consider it more of a long-term investment in less hassle rather than a total replacement for chemicals.

I looked into UV vs. ozone for a while and ended up going UV this season. What I’ve noticed most is how steady the pool stays between tests. Before, I’d get little spikes or dips after a heavy swim day or rain, but now things hold level a lot longer. Still running chlorine as a base, but I’m definitely adding less than before.

For me, the biggest perk wasn’t “less work” but less chasing numbers. The upfront cost was a bit of a gulp moment, but if you’re in it for the long haul, I think it pays off more in peace of mind than in cutting costs right away.

 

[Matthew Collins]

I added a UV system earlier this year, and while it hasn’t eliminated chlorine, it’s definitely made the pool easier to manage. The water looks brighter, and I’ve cut down on that strong chlorine smell that used to hang around. What I didn’t expect was how quickly the water clears up after a busy weekend, before, I’d usually shock right away, but now it bounces back faster on its own.

The catch is you still need to keep your chlorine at a safe baseline, and you’ve got to make sure the pump is running long enough for the UV to do its job. Once I tweaked the run times, it really started to shine.

If you’re hoping to ditch chemicals completely, you’ll be disappointed, but if you’re after steadier water quality and a little less effort, I’d say it’s worth the upfront cost.

I’ve been running a UV system alongside my regular chlorine setup for a while now, and it’s been a nice upgrade. The water feels cleaner, stays clear longer, and there’s much less of that harsh chlorine smell. It doesn’t replace chlorine, you still need a baseline, but I’ve noticed I use less overall and the pool recovers faster after heavy use. The key is making sure the pump runs long enough for the UV to treat all the water. Not a magic fix, but it definitely eases maintenance and keeps the water more balanced.

 

[Brandon Hayes]

I’ve helped maintain a couple of pools that went the “add-on” route rather than straight chlorine-only, and the biggest difference for me wasn’t just clarity, it was how forgiving the water became. Small mistakes that used to snowball (missed a test day, sudden weather change, extra swimmers) didn’t spiral as fast.

One thing people don’t always factor in is where these systems shine. UV tends to be great at keeping things polished and predictable, while ozone feels more noticeable when the pool gets stressed, like after storms or back-to-back swim days. Neither one magically fixes poor circulation or lazy maintenance, though. If the basics aren’t solid, the tech won’t save you.

Cost-wise, I’d say it’s worth it if you plan to stay in the house for a while and you’re already consistent with care. If you’re hoping it replaces chlorine or lets you ignore testing, you’ll be disappointed. But if you like smoother water behavior and fewer “what the heck happened?” moments, the upgrade does earn its keep.

In my experience UV and ozone feel more like an add on than a chlorine replacement, so you and I usually get more comfortable water with lower chloramine smell and sometimes steadier clarity, but the core maintenance stays the same, you still maintain FC matched to CYA, pH, and filtration, so it’s worth it if you have heavy bather load, sensitivity to smell, or ongoing chloramine issues, but if your pool is already clear and stable the improvement can be modest versus the upfront cost.
