Absolutely Loving HTH 3″ Chlorine Tabs!
I’ve been using HTH 3″ chlorine tabs all season, and they’ve made pool care a total breeze. Each tab comes individually wrapped, so there’s no sticky mess or fuss when you reach into the bucket. Just tear off the wrapper, drop the tab into your floating dispenser (or skimmer basket), and you’re set—no measuring, no spills, no guesswork.These tabs dissolve evenly, keeping our chlorine levels rock‑steady day after day. We’ve had amazingly clear, sparkling water with zero green tinge or cloudiness, even when temperatures heat up in the peak of summer. I love that I can set it and forget it for several days, freeing up more time for swimming and less time worrying about chemicals.HTH has always been my go‑to brand, and these 3″ tabs prove why. They’re economical (one bucket lasts us most of the season), super easy to store, and compatible with any standard floating chlorinator. I only trust HTH in our pool—and these tabs deliver every single time. If you want a no‑hassle way to keep your pool clean and swim‑ready all summer long, give HTH 3″ chlorine tabs a try! 10/10 recommend.

Perfect to keep your water blue
Love the chlorine tabs for our above ground pool. We use about 2 tabs every 2 1/2 weeks and our pool has yet to turn green.

A good match for my CL200 Chlorinator
These Tabs worked well in my Hayward CL200 Chlorinator. They lasted about a week with the CL200 set at 2, but my Water Test showed slightly under 1.0 PPM. So I've changed the CL200 setting from 2 to 4. If I can get to between 1-4 PPM, with Tabs that last 5 or more days without disintegrating, I'll be happy and do a little fine tuning from there. Sustained 2.0 PPM would be outstanding. In a container of 10 individually wrapped Tabs, 1 was broken. In my humble opinion, I think the broken Tabs are more of a shipper-handling problem than a MFG problem. Perhaps a layer of Bubble Plastic in the Container bottom would help. For now, I am satisfied with the product.

Slow to arrive
Product is fine. You can’t be in a hurry for it. It took two weeks to be delivered

Well packaged, works great
These tablets are individually wrapped which make the container a pleasure to open without being overwhelmed with chlorine odor. The tabs are easy to open. Do a nice job maintaining chlorine level.
