HTH 42051 Swimming Pool Care 3" Chlorine Tabs Advanced, Swimming Pool Chlorinating Sanitizer, 8oz

I use one of these tabs in conjunction with a floater in my cold plunge setup (chiller, pump, strainer) to keep the water clean and sanitized. Each tab lasts several weeks and does the job well.

Great price for the amount of pucks.

These saved my water clarity they are durable and fit nicely in a 3 inch chlorine floater. Ever since I used these my pool water is clear.

It's do it job on the pool

Puts chlorine in the water along with stabilizer to get your cyanuric acid up. So it does exactly what it's supposed to do. Like other reviews though, half the tablets will come broken up into crumbled pieces. Doesn't really matter. You can put everything in your chlorinator the same way. Would be nice if they were a little bit cheaper especially since it seems like they're selling broken ones at full price when they should be considered slightly defective and cheaper but whatever. This is way cheaper than the pool stores. Especially if you're like me and only needed 8 to 10 tablets to get that stabilizer level up to where it should stay for the rest of the summer. No point in buying a $200 bucket to only use a few of them.

Tablets Dissolve Completely in the strainer, less need for liquid Chlorine!

Just needed a few tablets for my pool. They work great

Just opened bought in May needed to finish last years supply. Most of the 3 inch tablets were broken and falling apart. Lots of chlorine dust at the bottom of container. Wish I would have opened it when I got it. Now I’m stuck with defective product. Never again beware not even sure if you can send back do to hazardous material.
