Been using these all summer. Water stays crystal clear. Haven't had to shock the pool once since switching.

What Pool Owners Are Saying

4.8 / 5
Our Pool Has Never Looked This Good
We have a 25,000 gallon in-ground pool and keeping it clean was always a struggle. Since switching to these tablets the water has been consistently clear — like genuinely blue and inviting every single day. I use them in the automatic feeder and they fit perfectly. No crumbling, no weird residue, no cloudy water. Just clean. Ordered two buckets and I'm already planning to reorder before the season ends.
Sandra R.
Finally — Tablets That Actually Last a Full Week
I've tried four different brands over the past three summers. Most of them dissolve in 3–4 days and I'm constantly refilling. These actually go the full 7 days like they say — even in 105 degree Phoenix heat. The water stays clear, the chemistry stays balanced, and I'm not spending my weekends fighting algae anymore. The 20 LBS bucket is also great value — I'm halfway through July and still have plenty left.
Jason W.
Pool Guy Approved — Switched Our Whole Client Base
I run a pool maintenance business and I've been testing these on our client pools for two months. The slow-dissolve formula is noticeably better than what we were using before. Chlorine levels stay consistent between visits, which means fewer emergency calls and happier clients. The pre-stabilized formula especially makes a difference in Florida sun — the chlorine actually holds. We're making the permanent switch across all our accounts.
Mark T.
Bought Two Buckets — Best Decision of Pool Season
Grabbed the 2-bucket deal and I'm so glad I did. Haven't had to make a single emergency pool supply run all summer. Tablets dissolve slowly and evenly, the water stays balanced, and the kids have been swimming every day without any issues. Super easy to use — just drop them in the floater and forget about it for a week. This is exactly what pool maintenance should feel like.
Lisa P.
Best Chlorine Tablets I've Used in 10 Years
Been maintaining my own pool for a decade and tried pretty much everything on the market. These are the best I've found at this price point. The 90% available chlorine is noticeably more effective than budget brands. Water clarity is excellent. Consistent dissolve rate. No chalky residue at the bottom. The sealed bucket keeps them fresh and dry between uses. If you're serious about your pool chemistry — these are the ones.
