Have been using pool shops for years and switched for price and quantity difference and have been pleased. Had this delivered to door and would tell anyone this is the way to get your pool supplies

Sams has the lowest price on chlorine granules of anywhere I've found, however my pool guy pointed out that the percentage of active ingredient is much lower than other more expensive brands so I have to use twice as much for the same result.

Have used this product for many years. It is high quality, it dissolves and elevates the chlorine levels in the pool quickly. Great to shock your pool or when you have to bring the chlorine levels up rapidly. I highly recommend it

Chlorine works

good price.

Pool shock

Good price

good deal

We mistakenly bought this thinking it was Poolbrand Chlorinating granules which is the best stuff on the planet. Our pool took little maintenance and the water was sparkling all the time. It took us half the summer to figure out that it wasn't. It cost us additional money for other chemicals. Over all it was the worst chlorine we have ever used. We would never buy it again. We returned it when we finally sat down and took a good look at the bucket and figured out it was Members Mark brand.

Have been using this product for many years with no problem. As of late, the brand has changed to Members Mark and my Cyanuric Acid levels went up dramatically. Had to drain and refill half of my 18,000 gallon pool to lower the level. Will be returning a recently purchased 50# tub and will no longer be purchasing chlorine products from Sam's Club.
