Good price but poor product. I used 2 buckets of this in a season and a half (in Georgia) before I realized this product is very weak and does not get the job done. I used to buy Poolbrand chlorine at Sams and never had an issue. I've been maintaining my pool for almost 20 years and never run into a problem with any brand of chlorine until using members mark brand. Oh, by the way, I returned half of the second bucket and sams gave me a refund.

I usually don't deviate from my original brand, but 50lbs for the price that Sam's was offering, was hard to pass up without giving it a try. So I had my water tested and my pool required 12-15 lbs of chlorine granules (shock). I put in the recommended higher dose of 15 lbs. Two days later I had my water retested and the test recommended another 10 lbs of shock. So I added about 12 lbs to be sure - and my water has yet to show progress after yet another 3 days. All other opening methods of back-washing daily and brushing have been included. There is no algae or debris in the pool as I have the filter and a robot constantly running. I don't know if chlorine expires, but the bucket I bought seems to lack potency. Reconsider!

There was a lot of price gouging going on right now because of a perceived shortage of chlorine tablets… Nice to know that Sam's Club is not participating and taking advantage. Not only is this a good value each individual tablet is individually wrapped which keeps the chlorine fumes at an absolute minimum until you're ready to use the tablet.

Awesome product at a great price! I've used it for more than 5 years and it works perfectly. Based on the negative reviews, I would recommend you check the active ingredients in this product against your other chemicals to ensure compatibility. I've used several different chlorine granular products, but none work better than this one.

I have been using this product since we installed our pool in 2009. I would use 50lbs a year. I have gone through 50lbs in 5 months. Only thing I can figure is the available chlorine has been lowered to save cost. I understand that the cost is out of Sam's control.

Love this stuff for our pool thank you Sam's

Works ok. Would be better if active ingredient was at a higher level.

Love this, we try to get it every year, 4 stars because it's still so expensive!

Way overpriced and definitely not as good as Clorox.

MembersMark pool chlorine is awesome. It works very well.
