Hot Tub Bromine Care Guide

Bromine is popular because it works well as a sanitizer in hot water. Balancing pH, alkalinity, and calcium hardness lengthens the life of your hot tub. It prevents corrosion. Weekly Stain and scale control prevents scale buildup from forming.

Pros: Bromine is widely available and fairly easy to use. It comes in tablet form, as well as concentrated powder.

Cons: Must be added constantly to maintain a bromine level.

Alternatives: Use a Nature 2 Spa Mineral Purifier to replace daily bromine use.
