    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 5-pound 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

    I manage some vacation rental properties which have spas and these chlorine tabs keep the water clear. The value is great and the quality is as good or better than other brands. For example, some other brands mention an chlorine availability around 50-55%. OnGuard has a chlorine availability of 90%. That means there is a lot less filler in these chlorine tablets so you get more bang for your buck. I would happily recommend this product.

    Former KemTek User

    When the chlorine shortage hit and I could not get Kemtek anymore, I found this product that claimed to be as good and for a better price. I tried it and loved it so this is my new brand. I was previously buying the 1-inch 4-pound Kemtek tablets and I get an extra pound of the Onguard brand for less money. I really have nothing negative to say. They shipped it very quickly. It is available on EZ Test Pool's website or Amazon. Thank you!
