SpaGuard Rapid-Dissolve Shock Oxidizing Tabs - 1.25 lb
Easy Non-Chlorine Shock Treatment for Clearer Spa Water
SpaGuard Rapid-Dissolve Shock Oxidizing Tabs make routine hot tub care simpler by replacing loose shock powder with convenient, single-dose tabs. Each rapid-dissolve tab helps oxidize non-living organic waste and contaminants introduced by bathers, including residues from body oils, sweat, lotions, and cosmetics.
Designed for spas, hot tubs, and swim spas, these non-chlorine shock tabs are a clean, measured way to refresh water clarity between soaks. Just apply the tab to the filter compartment with the pump running, let it disperse, and keep your spa maintenance routine fast, consistent, and easy to manage.

Product Details
Compatibility and Requirements
SpaGuard Rapid-Dissolve Shock Oxidizing Tabs are designed for use in spas and swim spas as part of a regular water maintenance routine. They are not a sanitizer replacement. Continue using the appropriate chlorine, bromine, mineral, salt, ozone, or other sanitizing system recommended for your spa.
Use these tabs after sanitizer has been added and when no bathers are in the spa. Because this is a non-chlorine oxidizer, it helps treat bather waste without contributing to the free chlorine residual. Some test methods may show a temporary false high total chlorine reading after use, so always follow label directions and your dealer’s testing guidance.
How to Use SpaGuard Rapid-Dissolve Shock Oxidizing Tabs
-
Make sure sanitizer has been added and the spa is unoccupied.
-
Put on gloves before handling the tabs.
-
With the pump running, apply 1 tab per 300 gallons directly to the filter compartment.
-
Allow the tab to dissolve and circulate through the spa water.
-
Wait 15 minutes before re-entry, provided water chemistry is within label recommendations.
-
Repeat weekly for routine treatment, or use more often after heavy spa use.
