Members Mark chlorinating tablets are the only ones we use in our pool. They are just as effective as any other brand that we have used to help keep the pool clean and they are much cheaper than any other place that sells them. If you have ever tried to lift this size container of chlorinating tablets, you know how heavy they are. Sam’s delivers it for free!! You don’t have to put it in your cart at the store or lift it out to put it in your vehicle, only to take it out when you get home. This is a huge bonus!!

This is the first purchase I have made of these Tabs, You can't beat the price ,and forty lbs of tabs is really super saving money. I have only used them for about 3 weeks, but they are working great if not better the Tabs I have purchased thru other stores.

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!!!

Love these tablets but to expensive

This is my second year buying these tablets and the work GREAT! The end of year price was fantastic.

Tablets work great! I use them in my automatic chlorinator. They are well packaged and a better value than ordering or going to the pool supplier.

These are great tablets. Have used them for many years now. Clears up minor algae and water clarity issues quickly.

Solid product, best prices compared to any other supplier. Packaged to protect the tablets better than others.

I have used the Tablets for years and like them but the new price is out of site but that is not Sam's fault.

Chlorine is still outrageously expensive, but Sams is cheaper than most. The 3" tablets are now individually wrapped which is nice... helps keep them fresh I suppose.
