HTH 42052 Swimming Pool Care 3" Chlorine Tabs Advanced, Swimming Pool Chlorinating Sanitizer, 5lb

works well

Great for the pools, the water looks crystal clear all the time.

I always buy these from Amazon because they're much cheaper than the pool store and they're exactly the same

Quality great! Did what it was supposed do

The tablet was broken however it still worked fine. I put it in a chlorine tablet floater and it lasted several weeks. The water seemed cleaner while using using this. I only docked one star because the tablet came broken and I lost about 10 percent of the tablet as a result because it was in small crumbles. I'd still recommend this.

Very strong chlorine tab. Good value. Pleased with the purchase.

It was nice to find a single package. I only needed one tablet before closing my pool for the winter. This brand dissolved nicely and was perfect for my needs.

We have an 8 foot Intex tube pool with a pump that is also intex but not the one they usually put with it but one made for a much bigger pool. We use this chlorine with it and our pool is crystal clear and up from March through October every year.
