I can put two of these in my chlorinator and the pool test extremely low chlorine. Both have dissolved in three days. I've used only these in the past, and during summer months I only needed 1 every five days for normal chlorine levels. Maybe I got a bad batch, but for 200$ I expected better.

I just want to say Sams club did not raise the price. The factory that makes 80% of Americas chlorine caught on fire. The new building is suppose to be up and running in January of 2023. Yes, the price was $99 last year and it’s not $199. I am not a fan of it either, but this product is the same and still doing what it did for the last five years I have been using this brand.

The chlorine tabs sold at Sam's used to be stabilized (contained CYA) and worked great for years for me. The last batch I bought (this product) no longer has stabilizer in it and I did not notice that. My stabilizer levels dropped to nil, which I finally figured out when trying to deal with stubborn cloudiness in the water. Now with CYA where it needs to be, and monitoring the water every day, I can't get chlorine levels up where they should be, no matter how high I turn up the feeder. Not sure what the problem is regarding that, but am switching to a brand from my local pool supply company.

I've been using these for several years with no problems. I live in Arizona and have an in-ground "play pool" that I guess to be about 18,000 gal. I put two tabs each into two floats, total 4 tabs, each week. That seems to keep the chlorine right where it needs to be. No significant chemistry problems attributable to these tabs.

Ease of ordering.

Good price for 40#

Member’s Mark chlorine tablets has the pool in tip top condition, for swimming this summer. The sparkling water is crystal clear and clean. Our pool's decorated finish & design looks beautiful. These tablets don't dissolve to quickly, doesn't burn your eyes. Great product

Bought these a month ago and thought we were getting a good deal.. Well, we got a good deal in the price, but not on quality.. It takes double the amount of tabs than any other brands I have used and have now ran into an algae issue I'm fighting all of the sudden after using these brand of tabs, definitely will not use these again..

Just what is needed for my sons gorgeous pool

Been using these for years.
