In terms of UV light exposure, how does bromine react compared to stabilized chlorine?

Bromine reacts faster to UV light exposure compared to stabilized chlorine. This is primarily because bromine does not have stabilizers, such as cyanuric acid, that shield chlorine from ultraviolet rays. While stabilized chlorine is protected by these stabilizers, allowing it to maintain its effectiveness longer in the presence of UV light, bromine is directly affected by the UV rays, which break it down more rapidly. Therefore, in environments with high UV exposure, bromine will lose its effectiveness at a quicker rate compared to stabilized chlorine, making it important for pool operators to monitor and adjust bromine levels more frequently in such conditions.
