Best tabs available

Great price, great strength, fast shipping! These tabs beat all heck out of what's available at the big box retail stores for getting and keeping your chlorine levels in range. Plus, I can buy enough to last the whole season in a single waterproof bucket that I can (and do) wash out and reuse when it is empty. Doheny's chlorine tabs are a staple for my pool and have been since the day I first learned that Doheny's existed many years ago. Highly recommend.

Years of Use A++

I have been using the 3" Chlorine Tabs from Doheny's for several years now. The one minor complaint I have is that occasionally I will have a few broken tabs in the 50# bucket. Other than that, my pool stays crystal clear. i would be foolish to use something else. The annual sale makes this the best option for my pool.

I like the 3" pucks. They are great!

I placed approximately 10 to 11 tablets into the chlorinator and refill in about two weeks. On occasion, I have received a damaged 50 pound container and crushed tablets. Since the tablets are individually wrapped, there is no waste, but I believe they dissolve faster when crushed. I do not believe this is a Doheny issue but more of a carrier not treating with care.
