Product Overview

SpaGuard® Rapid-Dissolve Shock Oxidizing Tabs are non-chlorine oxidizer tablets for spas and swim spas. The label says they eliminate non-living organic waste and contaminants, such as body oils, sweat and lotions, and are buffered to prevent pH bounce, and regular use helps keep the water clear. They contain potassium peroxymonosulfate and are compatible with spas and swim spas that use chlorinating or brominating products as the sanitizer. One bottle treats an average-sized spa for 12+ weeks, and the net weight is 1.25 lb (567 g).

The dose is 1 tab per 300 gallons of spa or swim spa water. Use it at start-up after the sanitizer has been added, then repeat weekly or as needed, when no soakers are in the water. Wearing gloves, place the tab directly in the filter compartment with the pump on. Soaking can begin 15 minutes after application. When the spa or swim spa gets heavy use, increase the dose to 1 tab per 200 gallons twice weekly.

These tabs are neither a sanitizer nor an algicide, so keep using your chlorine or bromine. The label carries the DANGER signal word: causes burns to eyes and skin, harmful if swallowed, and irritating to nose and throat. Wear safety glasses and rubber gloves, avoid breathing dust, and do not mix them with any other chemicals. Keep them in the original unopened container until used, stored in a secure, cool, well-ventilated place away from children and pets.
