More Details
Main highlights
- Stable in High Temperatures: Bromine is more stable than chlorine in higher temperatures, making it ideal for hot tubs, where heat can break down chlorine more quickly.
- Low Odor and Less Irritation: Bromine is less irritating to the skin and eyes compared to chlorine, making it a preferred option for swimmers with sensitive skin.
- High Bromine Strength: In The Swim 1-inch Bromine Tablets Plus offer enhanced sanitizing power with 98% active ingredient, an improvement over our regular bromine tablets that contain 96%, ensuring stronger disinfection in pools and spas.
- Effective at Higher pH Levels: Bromine remains effective at higher pH levels and can be reactivated with an oxidizer, providing greater flexibility in water chemistry management and more efficient use with fewer additions.
- Effective Sanitizer: Bromine is an excellent alternative to traditional shock sanitizers in swimming pools, spas, and hot tubs, effectively eliminating bacteria, viruses, and algae to maintain clean and safe water.

BROMIGUARD

1.2LB Bromine Tablets for SPA Hot Tub, 1 inch Tablets, Hot Tub Bromine Tablets, Soft Water Feel, No Chlorine Odor, Great Chlorine Alternative

BROMIGUARD

$23.52

More Details
Main highlights
- NO CHLORINE ODOR: Bromine tablets for spa hot tub have a gentler smell compared to hot tub chlorine tabs. The treated water will not leave behind a strong bleach tablets odor like spa chlorine tablets, making it more suitable for sensitive users and creating a more comfortable soaking experience.
- LONG-LASTING EFFECT: These spa bromine tablets dissolve slowly and last 5–7 days, providing continuous sanitation with fewer applications. They effectively kill bacteria, control algae growth, and help soften the water for enhanced comfort.
- EASY TO USE: Simply place the spa bromine tablets for hot tub into your floater or dispenser—no stabilizers needed. The bromine tablets 1 inch - 1.25 inch fit most spa and hot tub dispensers. Just check buoy size before purchase.
- BETTER THAN CHLORINE FOR SPAS: Bromine for hot tub performs more effectively than chlorine tablets in hot tubs because bromine stays active in a wider pH range (7.0–8.4) and its byproducts (bromamines) still retain disinfecting power. This ensures consistently clean water without the harshness or inefficiency often found with hot tub chlorine.
- 98% ACTIVE INGREDIENTS: BROMIGUARD bromine tabs contain 98% 1-bromo-3-chloro-5,5-dimethylhydantoin (BCDMH), with 61% available bromine and 29% available chlorine. Unlike hot tub chlorine tablets that lose strength in hot water, hot tub bromine tablets remain stable at high temperatures (35–40℃ / 95–104°F), making them ideal for spas and hot tubs.
