Historically, chlorine has been used the longest in the spa industry and it tends to be popular due to its ease of use and lower cost. It is an effective means for sanitizing spa water and killing bacteria. Granular chlorine can be applied directly to spa water to protect bathers against contaminants. Chlorine can be stabilized against UV degradation, so it is often the ideal choice for outdoor spas that are exposed to sunlight.
