Doheny’s 3-Inch Stabilized Chlorine Tablets | 99% Pure Tri-Chlor, 90% Available Chlorine | Long-Lasting, UV-Protected, Slow-Dissolving Pool Sanitizer | Individually Wrapped, Childproof 10lb Bucket

Finally I found long-lasting, and potent little chlorine pucks! The Clorox and HTH brands are horrid. Have fillers. And each of their puny pucks last less than 48 hrs. These are a huge improvement. No fillers and each one lasts 3-4 days. Making them much more effective and economical. Never going back.

Keeps the pool clean!

These are the best tablets i have found that out perform other tablets I have used. Last longer so I dont have to replace so often. Will keep buying these.

I estimate there are about 90 tablets of chlorine in the bucket. They are all individually wrapped. As you get 3/4 of the way down there are more and more broken tablets. Some just split in half and still wrapped, about 15 percent of them totally fallen apart, with powder and small pieces out of the wrapping. But I don't know how that can be prevented other than to manually set them into the bucket in carefully stacked rows that support each other. That would be time consuming. Other than that they do the job.

Must know a bit about pool chemistry before tossing tablets around. I've seen pool companies use tablets completely wrong or drop them in filter baskets. Know what you're doing. That said, it's a quality product at a quality price

High quality chlorine. Less expensive than many other brands.

Having delivered to your door is great. Each puck is individually wrapped. A must. I have used products that were not wrapped in the past. They stick together, seem to break easier and the odor is very very strong. I will continue to purchase this each year.Lid is easy to open as well, and stays closed tihht. No strong odors come out when closed.

I have ordered from Doheny’s before. I have always received my orders in a timely fashion. Their prices are always competitive, and usually the lowest.The chlorine tablets I ordered had the highest available percentage of chlorine, which work well, even in the Arizona sun.I would buy from them again.
