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!!!

Great Product! Great Price!!

This pool tables are working really well! After putting it in the pool, the water quality becomes clear and clean, without any strong chemicals smell. It's very easy to use, and the sanitizing effect is noticeable. The water looks crystal clear. It's also great value for money, I will definitely repurchase!

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.

2nd time buyer

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!

Good thing  for pure pool

Great product - arrived very quickly.  Not one piece was broken and the chlorine concentration is higher than others.

Great buy!

Buying them again, love that they are individually wrapped.

Individually Wrapped

All individually wrapped at a good price delivered

Wish I could say that these invidually wrapped chlorine tabs were not broken. Nearly every single tab in the bucket was broken and  these were the fastest dissolving tabs I have used compared to others. They tabs do not last at all.

Broken and fact dissolving

I received a 40lb. tub of chlorine dust. Most of the tabs that I pulled out were cracked and disintegrated. Can't pit that in the chlorinator or it will clog it. I ordered for the ease of having it delivered but it would've been better to go to the pool store and get better quality chlorine tabs.Instead I spent a lot of money for garbage tabs that are mostly unusable

ABSOLUTE CRAP

The item is titled members Mark 99% pure chlorine tablets, but even on the front it states it’s only 90% chlorine. That’s a big difference.
