These are all I'll ever use

I use these all the time, but I switched to a cheaper brand. I got off Amazon and I was regretting it within a month. I had to fight the algae twice as hard with these cheap no brand Amazon chlorine tablet I went back to the HTH tablets and my water is crystal clear again. I won't I won't ever use anything but again.

These chlorine tablets do good. Just don't drop these or any other chlorine tablets into your pool without first putting them into a chlorine dispenser. I learned that the hard way.

Great really works

I have used the Clorox brand and th other brand they sell but this one is the best one of them all. This brand is the only one that kept my pool crystal clear, even with Clorox it turned cloudy an green not with this.
