We like being able to buy the big bucket

This is Barnie. He holds our chlorine tablets and floats around to keep our pool clean. Currently Barnie is very hungry. As you can see he is floating. He will be fed 3 chlorine tablets today. All joking aside, we like buying the large bucket. It lasts, and is very convenient. The Sam's club brand works just as well as the name brand

Great Product! Great Price!!

I purchased this last week and it was delivered the next day. The tabs were individually wrapped. None of them are broken like other ones that I have bought from Leslie‘s. It is 99% chlorine! Better and less expensive to buy them from Sam’s Very Impressed!!!

Good thing for pure pool

A truly excellent shopping experience—the logistics were smooth, and I am very satisfied with the product. We have been using these chlorine tablets consistently; they are highly effective at keeping our pool water crystal clear. Highly recommended!

Great tablets for a good price.

I've used these tablets in my in-ground pool for several years and they work great! They are also the cheapest I've found chlorine tabs in the past couple of years.

Recommend!

We used these chlorinating tablets all summer in our 18ft above ground pool. They work great & don't seem to dissolve too quick in the dispenser. I do like the individual wrapped tabs. It keeps them contained and I didn't have breakage.

2nd time buyer

Purchased this again from Sam’s for the 2026 season. I bought it last year and I love how they came individually wrapped and in a big bucket. I saw a review that theirs were broken but my tablets are in perfect shape. I also like that they are 99% chlorine! Buying the big bucket will last me all season and works out much less expensive than buying anywhere else.

Love a Good Bargain… Hate the Chlorine Smoke Bombs

No complaints about how these tablets perform—my pool stays clear, and the price is solid. But the last couple of buckets have been a whole different experience. So many broken tablets, and every time I open one of those individually wrapped “gifts,” I get a face full of chlorine powder. I’ve literally had to start wearing a mask just to open them. Not exactly what I expected from a bucket of pool supplies. Still worth it for the results, but seriously… can we get less of the airborne drama?

Smaller price comes with a smaller size

The chlorine tablets are a quality product, however, customers should note that although the price has come down, so has the size. What used to be a 50lb bucket of chlorine tablets is now 40lbs.

Great price, inconsistent quality

chlorine after all is a commodity.. really good price, seems to work like all the others yet. one big problem with this.. half of the tablets were crumbling. we fell apart when I took them out of the bag.. I could be wrong but I really have a feeling they were sitting in the warehouse for quite a while. they seem to work just as good, just really old..

Not worth it!

Another excellent example of Sam's Club pricing that diminishes the cost of membership. Price is exactly the same at other pool supply outlets. Most pool company technicians do not like the individually wrapped tablets so I had to return for a refund.
