Been buying this product for years. Very strong and potent. Love going to pool store to test the water and they always tell me my levels are always right on. Always ask me what chlorine you using and i tell them and they say its strong stuff.so please buy it you won't go wrong five stars here

First time buyer from Sam’s so far fantastic. Ordered and delivered to my front porch next day. No more taking the old truck to the pool store and struggling with the heavy container. These tabs are working great pool water chem test are spot on. Packaged very nicely too.

Don't buy! CRUMBS! Only 6 whole, 10 in halves or thirds, all the rest - pebbles to granules! When I ordered these online my only delivery option was for them to be shipped. Box was fine, bucket was fine. I prefer to sit and cut all of the bucketful out of their wrappers when I first get them. As I was cutting, I found that they were all pretty much horrid. Then, for a refund, I had to drive to and lug the 40lb bucket back into a store. Never again!

I have been using Sam's 3" chlorinating tabs for several years. 20'X40' pool is open from April - October; summertime temperatures mid-80s-90s most of the time. I never need to add any additional chemicals; shock, algecide, PH+ or PH- during these 7 months. Testing each Saturday shows 7.6ph consistently with ability to clearly see a penny at the 8.5' bottom all the time. A great value!

Was looking purchase chlorine tabkets for the season. Have used these before with positive results. Theybwere in stock even with the national chlorine shortage at Sam's regular price. Everywhere else they were in stock the prices were highly inflated!

I read a lot of reviews on using Sam's brand chlorine tabs. Some said the tabs were not as good as products from pool stores. I have lived in a house with an in-ground pool for 3 summers now and the tabs work. I have a crystal clear pool and I love the lower price.

Shop and compare. This offering by Sam’s is competitively priced in a quantity that means it will last. All of the pucks are individually wrapped (easily removed) to insure freshness and it protects them from breakage during shipping. Heavy duty reusable bucket. Free shipping for Sam’s+ members makes the deal even sweeter. I will definitely buy them again...way down the road.

The tabs are packaged individually and that is nice. Many of the tabs are broken, not so nice.

Have used before for pool. Great product great price.
