Product Overview

SpaGuard® Rapid-Dissolve Shock Oxidizing Tabs are non-chlorine shock-oxidizer tablets for spas and swim spas. The label says they quickly oxidize non-living waste and contaminants, and one bottle treats an average-sized spa for 12+ weeks. Net weight is 1.25 lb (567 g).

Use the number of tablets the label directs for your spa's volume, added with the circulation running, as a routine oxidizer and after heavy use. The tabs oxidize contaminants but do not sanitize, so keep your chlorine or bromine level up. Follow the full directions on the label.

The label carries the DANGER signal word: causes burns to eyes and skin, harmful if swallowed. Avoid contact with eyes and skin, never mix them with other chemicals, keep the bottle dry and tightly closed, and keep it out of reach of children. SpaGuard® Spa Shock-Oxidizer is the granular alternative.

    • 1. Test and balance the water.
    • 2. Add the number of tablets the label directs for your spa's volume.
    • 3. Add them with the circulation running.
    • 4. Repeat as a routine oxidizer and after heavy use, as the label directs.
    • Signal word: DANGER. Causes burns to eyes and skin. Harmful if swallowed.
    • Avoid contact with eyes and skin.
    • Never mix with other chemicals. Keep dry and tightly closed.
    • Keep out of reach of children.
  • Non-chlorine oxidizing breaks down bather waste so your sanitizer can work. Keep your chlorine or bromine level in range, and use the other SpaGuard® Rapid-Dissolve Tabs to keep pH and alkalinity balanced.

    • One 1.25 lb (567 g) bottle of SpaGuard® Rapid-Dissolve Shock Oxidizing Tabs, part number 42664BIO
