SpaChoice Sodium Bromide Bromine Booster for Hot Tubs — 1 lb 4-Pack, Establishes Bromide Reserve

SpaChoice Premium Bromine Booster is a sodium bromide powder used to create a stable bromide reserve in hot tub and spa water before using brominating tablets.

Keep your spa ready for bromine-based sanitation with this 1-lb 4-pack of sodium bromide. This product is not a sanitizer on its own; instead, it builds the bromide reserve that brominating tablets convert to active bromine. It’s especially useful the first time you convert a fresh fill to bromine treatment and after each drain-and-refill cycle. Simple dosing and tablet compatibility make it practical for home spa owners who prefer bromine over chlorine.

How do I use this bromide booster with bromine tablets?

Add the SpaChoice sodium bromide to establish a bromide reserve before introducing brominating tablets. Once the recommended bromide level is present, brominating tablets will generate active bromine for sanitizing the water. Always follow the tablet manufacturer’s instructions and test water regularly.

• Add 1/2 ounce of product per 100 gallons of spa water to reach about a 30 ppm bromide reserve.
• Dissolve or broadcast evenly across the water surface, then circulate with the pump for several minutes.
• Introduce brominating tablets once the bromide reserve is established for ongoing disinfection.

When should I add sodium bromide to my hot tub?

Use this product whenever you first switch to bromine-based sanitation and after each time you drain and refill the spa. Establishing the bromide reserve before adding tablets ensures the bromine chemistry works efficiently. Repeating the process after fresh fills keeps treatment consistent.

• First-time bromine system setup on a new or freshly filled spa.
• After each drain-and-refill cycle to re-establish the bromide reserve.
• When switching from chlorine to bromine treatment for ongoing maintenance.

Is this product a sanitizer and how does it differ from brominating tablets?

SpaChoice sodium bromide is not a disinfectant; it provides bromide ions that brominating tablets convert into active bromine. Bromide booster alone won’t sanitize water—tablets or another approved sanitizer are required to kill contaminants. Think of the booster as the necessary precursor that enables bromine tablets to work properly.

• Booster = source of bromide ions (reserve), not an active sanitizer.
• Brominating tablets react with bromide to produce the active bromine sanitizer.
• Using both together eliminates chlorine-related odors and maintains bromine-based sanitation.

How do I measure and dose the product accurately?

Accurate dosing keeps bromide levels where they should be without overshooting. A kitchen or spa-grade measuring tool that reads ounces works well for the specified 1/2 ounce per 100 gallons ratio. After adding, run the spa circulation and test water chemistry to verify the reserve before adding tablets.

• Measure 1/2 ounce per 100 gallons using a calibrated scoop or measuring spoon.
• Pour in while the pump is running and allow a few minutes for circulation.
• Test bromide/bromine levels with appropriate test strips or kits and adjust if necessary.

Who this is for: SpaChoice Premium Bromine Booster is designed for spa and hot tub owners who prefer bromine sanitation, operators converting from chlorine, and anyone who wants a straightforward way to establish a reliable bromide reserve. It’s suitable for residential spas and hot tubs where brominating tablets will be used for ongoing disinfection. Not intended as a standalone disinfectant—always pair with brominating tablets and routine water testing for safe operation.
