Does a UV system noticeably reduce chemical use, or is it more of a supplemental thing?
Is anyone using UV systems for sanitation?

Yeah, we installed a UV system last summer. It’s definitely more of a supplement it helps sanitize what passes through the system, but it doesn’t leave anything behind like chlorine does. I still use chlorine regularly, but I’m not shocking as often and I’ve noticed my water stays clearer between treatments.

Using UV here too. It does cut down on some chemical demand, but you still need a sanitizer in the water. Think of it like backup: UV knocks out bacteria fast when it flows through, but chlorine’s still doing the day-to-day work in the pool. It’s made our water feel cleaner, though, and we’ve had fewer issues since adding it.

I’ve been using a UV system along with chlorine for a couple of seasons. It doesn’t replace chlorine, but it definitely helps reduce how quickly I burn through it. The water feels cleaner and clearer, and I don’t have to shock as often. I still maintain a small chlorine residual, but the UV makes overall maintenance less stressful.

I use UV with chlorine not a replacement. UV knocks things down as water passes, so I shock less and the water feels cleaner. But you still need a small chlorine residual for safety

I use UV with chlorine, not as a replacement. UV helps reduce chlorine use because it kills bacteria faster, but you still need chlorine for safety.

I added a UV unit a couple seasons back after a rough stretch where the water would look fine, then smell “used” after a busy weekend. Chlorine was in range, but combined chlorine kept creeping up and shocking all the time was a pain in the neck. That’s what pushed me to try UV, not because I wanted to go chemical free, just wanted fewer problems.
In practice it’s 100 percent supplemental. UV only works on what passes the lamp, so there’s no residual in the pool. Chlorine still does the heavy lifting day to day. Where I noticed the difference was chlorine demand and smell. CC dropped, water stayed clearer between cleanings, and I shock way less now. It also helped after high bather load days when sunscreen and sweat would normally turn the water dull even with decent FC. You still need to watch pH drift and keep circulation solid or the UV doesn’t get a fair shot.
I wouldn’t expect it to replace sanitizer, but as a support piece it actually worked. I still keep a normal chlorine level and use stuff like aquadoc non chlorine shock when the water feels tired instead of hammering it with more chlorine. For me it made maintenance calmer, not magically easier. Anyone else notice UV shines most when everything else is already dialed in?

UV is more supplemental, you and I usually won’t cut chemical use by a lot because chlorine still has to be maintained as a residual in the pool, but UV can make things feel more stable with less chloramine smell when circulation is good.

From what I’ve noticed personally, a UV system can reduce how much chemical work you need to do, but it’s not a full replacement. The water feels steadier and cleaner, so you’re not constantly adjusting things. Still, I think you need a baseline sanitizer in place, because UV alone doesn’t cover everything day to day.
