SpaGuard Rapid-Dissolve Chlorinating Tabs - 1.25 lb
Quick-Dissolving Chlorine Tabs for Easy Spa Sanitizing
SpaGuard Rapid-Dissolve Chlorinating Tabs offer a simple, single-dose way to sanitize and oxidize spa, hot tub, and swim spa water. These 1-inch rapid-dissolve chlorine tabs are designed to disperse quickly, helping maintain a proper free chlorine residual while supporting clearer, fresher water.
Each tab treats 300 to 600 gallons of spa water and is made for convenient weekly hot tub maintenance. Instead of measuring loose granules, just apply a tab with the circulation pump on, allow it to dissolve fully, then test the water before re-entry.

Product Details
Compatibility and Requirements
SpaGuard Rapid-Dissolve Chlorinating Tabs are designed for spas, hot tubs, and swim spas that use chlorine sanitizer. They are different from SpaGuard Rapid-Dissolve Shock Oxidizing Tabs, which are non-chlorine oxidizer tabs.
Use these chlorinating tabs only as directed on the label. Always test your spa water with test strips or a test kit, allow the tab to dissolve fully, and confirm the free chlorine residual is between 3 and 5 ppm before re-entry. Do not enter the spa if chlorine levels are above 5 ppm.

Turn on the circulation pump and jets.
