    • These work Awesome!
Size: 5 lb.
I like that each comes wrapped separately. None broken in pieces. Total of 10 came in the 5-lb size container. These seem to work the best in our round above ground pool. 1 weekly tablet for 18ft x 4ft high pool. I also add 1 arm & hammer pool ph stabilizer tablet with the chlorine tablet floaty to keep ph great.. and shock every 2 weeks.. sooooo easy! Testing is always perfect! Had my pool 16 years now. ... show more

    • Chlorine 3” XTRABLUE tablets are effective and easy to use in floating dispensers.
Size: 5 lb.
Box arrived sealed. Chlorine tablets are very strong I suggest opening outside. They fit nicely in the KingSom dispenser. Designed for algae removal and maintenance. Suggest brushing walls of pool and steps to accelerate chlorinating and promote even dispensing. I can’t address chemical free aspect but even within a few hours I can see the chlorine is having a positive affect. Container does reseal but does not lock. I suggest placing in a safe place to keep away from children. ... show more

    • Great buy!
Size: 5 lb.
I use these in my above-ground pool and they’ve done a good job keeping the chlorine level up between treatments. Easy to use in a floater and dissolve at a steady rate. No complaints.

    • This will keep algae away and make water crystal clear
Size: 5 lb.
This product works great for keeping your chlorine levels where they should be and helps keep your water clean and free of algae. One tablet last about 2 weeks which is good. I use a float that holds about 3 of them so I set it and forget it. My only issue with these tablets is that they can’t be used the next year. Seems like they lose their effectiveness after awhile. I had 2 tablets left over from the previous year, used it and they literally only lasted like 2 days. So I knew I had to buy more. ... show more

    • Great 4 pools!

    • Crystal Clear Water!
Size: 5 lb.
Not only does this keep my pool blue all season long, it does not irritate the skin for my kids or guests. So many other brands feel harsh and won’t get rid of the green/cloudy color. This is by far the best chlorine on the market.

    • CLOREX, GREAT FOR KEEPING YOUR POOL CLEAN
Size: 35 LB
Excellent for keeping your pool water clean, use with the Clorex Liquid Pool Cleaner for a no hassle summer pool season. I have saved money, time, and stress using these products. Costs more, but my time is worth money too. I only buy these two products for my pool.

    • Broken tablets and crumbs
Size: 35 LB
I bought a 35lb tub of these tablets last time and most of them were broken up into small pieces and crumbs. If I'm gonna be paying this kind of money for pool tablets shouldn't they not be all broken up? I chose to go with a different brand this time which was a better value per pound. No, I wouldn't recommend this Clorox brand due to the high price for busted up tablets and crumbs. ... show more
