- Kekoa808Crystal clear pool all summer.I’ve been using the Clorox Pool&Spa XTRABLUE 3” tablets for two seasons now, and they’ve made pool maintenance so much easier. Each tablet is individually wrapped, which keeps them from crumbling or sticking together in humid weather, a huge plus compared to other brands.
They dissolve slowly and evenly in my floater, keeping chlorine levels steady for a week or more depending on weather and pool usage. I’ve had zero issues with algae or cloudy water since switching to these. The “extra blue” formula really seems to help with clarity, the water sparkles after just a day of use.
The only downside is the smell when you open the bucket (it’s strong, like any chlorine product), but that’s expected. For the quality and convenience, it’s worth every penny.
Highly recommend for anyone who wants to spend less time fussing with pool chemistry and more time swimming! - Sandy C.Keeps my pool sparkling clean!I’ve been using Clorox Pool&Spa XTRABLUE Chlorinating Tablets for a few years now, and they’re fantastic! These tablets keep my pool water crystal clear and balanced. They dissolve slowly and evenly, maintaining the perfect chlorine levels without any hassle.
I’ve noticed a huge difference in the water clarity—no more cloudy water or buildup around the pool. The tablets are easy to use, and I love that they’re specifically designed to last longer and provide consistent protection.
If you want a reliable, effective way to keep your pool sparkling clean, these chlorinating tablets are a must. Highly recommend! - Era DeloachGood valueGreat product
- Judith L. DiFioreGreat tabs but arrived broken up!These are truly the best chlorine tabs I've ever used 25 years! But in the last two deliveries, the wrapped tabs were all broken up within the wrappers. The wrappers were slightly opened so there was dust everywhere when adding to the chlorinator, and small pieces dissolve too quickly.
- J. MacLeodCrystal clear water with minimal effortWe’ve had a hot tub for about five years — one of the big ones, sits eight, deep enough for my wife to do calisthenics and aerobics. Until COVID, we were using traditional powdered chlorine, but prices went up, and I decided to try something different. Enter Clorox Pool&Spa XTRABLUE 3” Chlorinating Tablets.
Here’s how we use it:
• Put a tablet in a floating dispenser, set to the lowest setting
• One tablet lasts 2–3 weeks in the hot tub
• We remove it when needed, stretching the tablet to last a month or more
Since switching, the water has stayed crystal clear — we haven’t changed any other chemicals except maybe the filters. Honestly, I’d estimate at least 50–75% of the improved clarity comes from this product alone.
If you want easier, longer-lasting sanitation without constantly fussing with powder, this is a simple, effective solution.
Do you want me to keep this in the same slightly casual, storytelling tone as your previous review for consistency? - MimiConvenient to UseWorks well in our pool. We have a saltwater pool but these chlorine tablets are essential for clear water.
