How to Activate Bromine in Your Hot Tub with Non-Chlorine Shock

How to Activate Bromine in Your Hot Tub with Non-Chlorine Shock

If you are using bromine to keep your hot tub water clean and balanced, you might be wondering why your bromine levels are not rising as expected. One of the most important steps in activating bromine is adding a non-chlorine shock. In this guide, we will explain exactly why this step matters and how to do it correctly.

Why You Need Non-Chlorine Shock to Activate Bromine

Bromine boosters add sodium bromide to your water. However, sodium bromide alone does not sanitize your spa. To transform bromide into active bromine sanitizer, you must oxidize it. This is where non-chlorine shock comes in. Non-chlorine shock (potassium monopersulfate) activates the bromide so it starts working to kill bacteria and keep your water fresh.

If you skip this step, your bromine readings will stay low, and your spa will not be properly sanitized. For the best results, always pair your bromine booster with a non-chlorine shock treatment right after application.

Step-by-Step: How to Use Bromine Booster and Non-Chlorine Shock

  1. Balance Your Water: Test and adjust pH and alkalinity to recommended levels before starting.
  2. Add Bromine Booster: Measure the recommended amount of AquaDoc Bromine Booster and sprinkle it evenly into your spa water.

  3. Activate With Non-Chlorine Shock: Right after adding bromine booster, apply AquaDoc Non-Chlorine Spa Shock to the water. This step is critical for converting the bromide into usable bromine sanitizer.


  4. Run Your Spa: Turn on circulation and let it run for at least 30 minutes with the cover open.
  5. Test and Adjust: After a few hours, test bromine levels. Adjust as needed to reach the ideal range (3-5 ppm).
