Just right

I like these chlorine tabs. They seem to last longer for some reason and they're simple to open and plop into the chlorinator . For our 35,000 gallon in ground pool I keep our automatic chlorinator set at 3 to 4 on a scale of 10. This provides a steady supply of stabilized chlorine and maintains the total and free chlorine levels just right. I'll add 5 or 6 tabs every week or so and we're good to go. We also use a variable speed pump with a cartridge filter system, on 23/7. (Uses less electricity than our constant volume pump). End result, Crystal clear sparkling water with just the right sanitation and chemistry. Good product, good price and quick delivery.

Great product and great customer service

First, I received this product 3" tablet (50 lbs) but there were about 15 tablets got damaged due to shipping from FedEx. I called and complained about the packaging process to prevent the future shipping. The agent immediately noted down, and offered a full replacement! He was very professional and apologized for what happened. After a few days, I received a brand new replacement ! I totally didn't think they will do that, but they did!! Also, the product was very good after using for 2 weeks. I have used different brands like Leslie or IntheSwim, and this Doheny's tablet is the top quality!! It is making my pool clean and fresh!

3" Chlorine tabs

Was a great deal. Pool supplies are getting more expensive so when I can get a great deal, I'll take it. I'm ready for the swimming season to arrive, but the weather is not being cooperative. It will be several months before swimming outdoors is possible(and comfortable😉) but I will be ready. Have ordered many products from your company and have no no issues.
