    5.0 out of 5 stars Pool must have
    Reviewed in the United States on October 9, 2024
    I bought these because Our above ground swimming pool needed tablets and these were the perfect size. I will say it has a very very strong smell of chlorine so strong that it left our hair and clothes smelling like chlorine so we had to do a little bit of math to change how many tablets we needed in order to maintain our pool clean. They would last about one week, maybe two without the tablets entirely dissolving. They’re very easy to use the box grab the tablets you need. I’d recommend gloves to handle these because they are very strong. They definitely helped control our algae or anything else that needed to be controlled in our pool.

    5.0 out of 5 stars Effective and Convenient - Keeps My Pool Sparkling!
    Reviewed in the United States on July 29, 2024
    I've been using the CLOROX XtraBlue chlorinating tablets for my pool, and I'm extremely satisfied with the results! These 3-inch tablets are easy to use and provide long-lasting chlorine levels, keeping my pool water clean, clear, and safe for swimming.

    I appreciate the convenient 5-pound container, which lasts a while and saves me from frequent purchases. The tablets dissolve slowly, maintaining a consistent chlorine level, and the XtraBlue formula helps prevent algae growth.

    I've noticed a significant reduction in eye irritation and skin discomfort since switching to these tablets. My pool water looks sparkling blue, and I have peace of mind knowing it's properly sanitized.

    Overall, I highly recommend the CLOROX Pool & Spa XtraBlue chlorinating tablets for their effectiveness, convenience, and value. Great product!

    5.0 out of 5 stars Love these, individually packaged is AWESOME
    Reviewed in the United States on August 11, 2024
    These are awesome, I only ordered them because the price seemed good. I had not realized they were individually packaged and that is AWESOME. The individual packages open very easy (when your trying), which is extra awesome too, I expected to need a little muscle and having to worry about the tablet flying out when it pops open but they open very smooth and easily. The individual packaging makes it much easier/safer transporting them to the pool chlorine float. Easy to drop them into the float without having to touch them. Can leave them outside without having to worry about moisture getting to them. Don't have to worry about opening a bucket of straight chlorine and getting hit in the face with harsh poison air that comes out of the bucket.

    And for their actual purpose, they do chlorinate well. Each tab seems to last about a week in our small above ground pool, and it has been crystal clear.

    3.0 out of 5 stars Good Product … But Disappointed
    Reviewed in the United States on December 13, 2024
    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.
