Clorox® Pool&Spa™ XtraBlue 3” Swimming Pool Chlorinating Tablets, Kills Bacteria & Stops Algae (25 LB)

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!

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!

Decent price compared to the store. I enjoy they are individually wrapped so I don't have to actually touch the chlorine and can instead just empty the bag into my skimmer or chlorine basket.

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.

These chlorine tablets do a solid job keeping the pool clear and clean. They dissolve at a steady rate and help maintain consistent chlorine levels without much effort. I’ve noticed fewer algae issues since switching to XtraBlue, and the water stays sparkling with minimal maintenance. The only thing to keep in mind is that the tablets can be a bit strong, so monitoring chlorine levels regularly is important. Overall, a dependable option for anyone looking to keep their pool in great shape.

I wish I would of found these sooner First time I did not have to fight a green pool all summer No running to the pool store the storage bin sealed nicely to keep them from any moisture The quality of this product saved my summer

I’ve been using these in our 6,000-gallon pool with no issues. During the hot months I put one directly in the skimmer once a week, and in the cooler months about once every two weeks. They’ve worked well and kept the pool in good shape. One thing to be careful of when adding them is splashing. I had water splash back a couple of times with some of the powder mixed in, which ended up ruining two shirts with chlorine spots. That’s not the product’s fault, just something to be aware of when handling them. Overall, they’ve been reliable and effective for my pool.

I love the tablets. They work great. Pool is clean. We’ve ordered the 25# container multiple times and I recommend them. The problem is, and if it happens again I’ll find another tablet, is the last 25# container came with each tablet individually wrapped and every single one of them was crushed to pieces. In some cases, maybe half the tablet was intact but the other half was crumbled to Tibet pieces. I thought maybe it was just the ones on the top so I just used them as I’ve had this product before. Today I grabbed 3 tablets and each of them was crushed. I finally decided to just look through each one and, sure enough, everyone of them is broken. I’ve still used these for the past 3 months, but it leaves chlorine powder all over the place when I open and place into the pool floater. I truly hope I never get broken ones again. It’s almost as if the containers just got thrown around or something.
