SpaGuard Rapid-Dissolve Shock Oxidizing Tabs clear and refresh spa water the easy way — a single, fast-dissolving non-chlorine shock tab you drop in once a week. Every time someone uses a spa, they leave behind body oils, perspiration, and cosmetics. That non-living organic waste is what irritates skin, stings eyes, creates odors, and clouds the water. Shocking — oxidizing — burns it away and restores clarity and comfort. These tabs make that weekly step effortless.

Because they’re built on a non-chlorine oxidizer (potassium peroxymonosulfate, or MPS), they shock the water without adding to your chlorine residual — so re-entry is a quick 15 minutes, not a long wait for chlorine to fall. The tabs are also buffered to prevent pH bounce, so a routine shock won’t knock your water balance out of range. And the effervescent, rapid-dissolve format means each tab fizzes apart and distributes its oxidizer quickly and evenly.

The convenience is the point: one tab per roughly 300 gallons, once a week, and a single bottle covers about 12 weekly applications in an average-sized spa. It’s the same non-chlorine oxidizing power in a grab-and-go tab.

Pro Tip: Don’t be thrown by your test strips after shocking. Like other products containing potassium monopersulfate (MPS), this one can make most test methods read a false high total chlorine level for up to 72 hours after application. That’s a known quirk of MPS, not a real chlorine spike — your free chlorine reading and your re-entry timing are what matter.
