'Doheny's is a Great Company With Quality Products and Price

I have purchased this product many times and will continue to purchase it in the future as the product is excellent and the price cannot be beat. The delivery is always by the next day after purchase. I purchased the 50 pound 3inch chlorine tabs a few days ago and added No More Problems to the order at a great price also.

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.

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.
