SpaGuard Rapid-Dissolve Shock Tabs are 1-inch, fast-acting chlorine tablets designed for hot tubs, spas, and swim spas, acting as both a sanitizer and a shock treatment.

You simply drop them into the filter well to use, as they are a convenient, blended, one-shot solution for maintaining clean and clear spa water.
