Key item features

  • 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.
  • 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.
  • 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.
  • 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.

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.

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.

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.
