Spa Shock and Oxidizer
Spa shock or oxidizer helps break down contaminants, refresh sanitizer performance, and clear used-up waste after soaking.
Why this chemical is used
Oxidizing is different from maintaining a daily sanitizer residual. It helps burn off organics from sweat, lotions, and heavy use.
When it is needed
Use the correct shock for your sanitizer system and wait until water is safe before soaking.
How to use it safely
- Test before adding anything.
- Calculate dose based on actual spa volume.
- Add chemicals separately with circulation running.
- Wait, circulate, and retest before adding more.
- Follow the product label and spa manufacturer instructions.
Small spas are easy to overdose. When unsure, add less, circulate, and retest.
