Hot tubs by nature should conjure up images of peace loving environmentally conscience folks who are doing their best to save the planet! However, the real nature of a hot tub is one where water is heated and in containment for a long period of time.
To keep the water in that hot tub safe and free of bacteria chemicals are needed.
Using Chlorine or Bromine
Primarily, disinfectants such as chlorine or bromine have been staples in the hot tub market for years. However, some may see these "chemicals" as something that can be harmful to humans or the environment.
In actuality the chlorine or bromine used in hot tub water care is some of the safest and innocuous chemical when it comes to water treatment. Both chlorine and bromine are categorized as "halogens" , meaning they both are formed from salt. And once they have cycled through the process of disinfection or oxidation in water they both convert back to a salt...it's kind of like the expression "from dust to dust", only in this case it's 'from salt to salt"!
As long as they are used properly chlorine and bromine are still two of the most effective and safest forms of water disinfection!
