Key item features

  • Effective Sanitizer: This bromine sanitizer effectively eliminates bacteria, viruses, and algae in swimming pools, spas, and hot tubs, maintaining clean and safe water.
  • Enhanced Strength: In The Swim 1-inch Bromine Tablets Plus feature 98% active ingredient, offering stronger disinfection compared to regular bromine tablets with 96% active ingredient.
  • Temperature Stable: Bromine is more stable than chlorine in higher temperatures, making it an ideal choice for hot tubs where heat can quickly degrade chlorine.
  • Gentle Alternative: This bromine option is less irritating to skin and eyes than chlorine, providing a preferred sanitizing solution for sensitive individuals.
  • pH Resilient: Bromine remains effective at higher pH levels and can be reactivated with an oxidizer, allowing for greater flexibility in water chemistry management.
  • Fast Dissolving: The 1-inch tablet size accelerates dissolution for quick sanitizing results, and approximately 31 tabs are used per 10,000 gallons every 5-7 days.
  • Brominator Required: These bromine tablets must be dispensed using an automatic brominator, with the brominator and pump running 12-24 hours daily depending on weather conditions.

Switching From Chlorine to Bromine

Shipping was quick and the packaging is perfect for regular use with my swimspa. Switching from Chlorine to Bromine is new to me, so I'll follow up with my experience for those of you considering the switch.

Great value, ease of use

Not only is this Bromine less expensive than any local pool supply shop in my area, it comes packaged in 10 %23 plastic bags in the bucket for very easy handling. Delivered to my home in 48 hours.

They are exactly perfect for our 15,000 plus gallon indoor pool. Although lately it seems as though the pool eats the bromine tabs up within a month now.
