SpaGuard Rapid-Dissolve Shock Oxidizing Tabs
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.

SpaGuard® Brand FAQs
What is SpaGuard?
SpaGuard is a professional-grade brand of spa and hot tub water care products — sanitizers, shocks, balancers, and water enhancers — formulated specifically for spas rather than adapted from pool chemicals. The line is designed to work together as a complete system for clean, clear, comfortable water.
Who makes SpaGuard?
SpaGuard is part of the BioGuard family of water care brands, a long-established name in pool and spa chemistry. That backing means the formulas are professionally developed and tested, with a reputation built over decades in the industry.
What water care systems does SpaGuard offer?
SpaGuard supports three complete care methods: a chlorine system, a bromine system, and the Soft Soak TRIO system. Each is a coordinated set of products, so you can match your routine to the sanitizer you prefer.
What makes SpaGuard different from generic spa chemicals?
SpaGuard products are engineered for the unique demands of hot, agitated, heavily used spa water, and they're built to work together as a system. That coordination delivers more reliable, repeatable results than mixing unrelated single products.
What is ALEX water testing?
ALEX is SpaGuard's exclusive computerized water-analysis tool used by its dealers. A quick water sample produces a precise read on your spa's chemistry and a tailored recommendation, taking the guesswork out of what to add and when.
Why buy SpaGuard from an authorized dealer?
SpaGuard dealers are trained on the brand's products and water-care technology, so you get expert advice alongside genuine product. They can run an ALEX analysis, troubleshoot issues, and recommend exactly what your water needs.
