SpaGuard® Spa Shock-Oxidizer is a powerful, buffered non-chlorine oxidizer and clarifier formulated specifically for spas and hot tubs. It removes organic contaminants such as body oils, cosmetics, and lotions while clarifying the water.
The unique buffered formula prevents pH fluctuations (“pH bounce”) and helps maintain water balance after treatment.
Works in as little as 15 minutes, allowing you to enjoy your spa shortly after use.
Compatible with all sanitizer systems — including chlorine, bromine, salt, ozone, and mineral systems — and ideal for weekly maintenance.
Quick-dissolving granules oxidize waste and restore water sparkle without adding chlorine residual or affecting sanitizer levels.
Regular use helps reduce unpleasant odors, foaming, and cloudy water, keeping your spa fresh and inviting.

Compatability

Directions

Test and confirm spa water pH (7.2–7.8) and sanitizer levels before adding.

With the circulation pump running, broadcast 2 oz per 300 gallons of water directly into the spa.

For weekly maintenance, add 1 oz per 300 gallons or more frequently with heavy use.

Allow water to circulate for 15 minutes before re-entry.

Retest sanitizer and pH levels after treatment; adjust if necessary.

Store tightly sealed in a cool, dry place.

Q: How soon after treatment can I use my spa?

A: Typically 15 minutes after treatment, once water circulation has mixed the product completely.
