The OnGuard 1” Maxi-Clor chlorine tablets were designed to disinfect pool water, eliminate mineral scale buildup, and clean your swimming pool water in a manageable size. Created to maintain a clear pool of all sizes, these chlorine tabs also have superior sun protection and a slow-release formula to slowly distribute chlorine to your pool over the course of days. Keep your family and friends entertained by the pool all summer long by keeping a supply of OnGuard pool chlorine handy. The 5 bucket contains approximately 180 tablets. OnGuard is a trusted name in pool and spa maintenance products. These super chlorinating tabs were designed to be easy and effective in sanitizing, chlorinating, and producing clean and clear pool water. OnGuard Chlorine tablets work well with vinyl-lined pools and salt systems. Apply the recommended number of tablets to feeders, floaters, or skimmer baskets using the instructions on the rear of the bottle as a guide. Active Ingredient: Trichloro-s-triazinetrione (99%).
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.
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!
