    Chlorine tablets for my spa

    I have been using these tablets in my spa for years. I recently had a hip replacement and needed to buy some but getting to my local store was painful and difficult. I ordered a bucket online from EZ Pool and Spa and the order went well. The shipping was fast, the price was fair, and the communication was good. Overall, I am pleased with the product and the company. Thank you. -Matt

    Readily Available During Chlorine Shortage Crisis!

    I switched to the Onguard brand recently when it was the only brand available because of the chemical shortage. It's performed well compared to past seasons with Clorox and Kemtek. The price isn't bad and as I mentioned, it's been in stock nearly all year. has been great. They ship quickly and have good customer service.

    Onguard chlorine tabs

    Works great in our 15' Summer Escapes pool. Keeps the water clear all summer. A single tablet lasts roughly one week. Overall the product works well for our setup.

    Great little chlorine tablets

    I have 2 floating chlorine feeders which I put in the pool when my family is not using the pool. I put a few tablets in it regularly and the water was clear! The size is great for slow dissolving but they also are convenient so I can add as much or as little as I need. I highly recommend getting these!
