The age old battle, Bromine or Chlorine? Do you need them and if so, which one?

Bromine and Chlorine are sanitizers for your Hot Tub, with out a sanitizer, you are basically stewing like a soup in your own bath of skin cells, soap residue, bacteria, skin products and more. Using a sanitizer is indeed completely necessary for the sanitary use of your Hot Tub, the next question is, which one should you use?

Chlorine is the age old solution, it has always been the most popular sanitizer. Bromine is becoming increasingly more popular and I prefer it for my Hot Tub, hopefully this article will help you to decide which is the best for you.

While chlorine is the most common sanitizer for swimming pools, bromine is used to sanitize hot tubs more often, with good reason.

Before you can make an educated decision about which sanitizer to use in your hot tub, you need to learn about their features, benefits, and drawbacks.


Chlorine is a chemical made using ordinary table salt, hydrogen, and sodium hydroxide. It is an efficient disinfectant and is used to help create a more sanitized life for people all around the globe. Most people are familiar with the word Chlorine, it is a popular household product similarly to bleach. Mainly, it is most known for keeping your water clean. 

If you choose to use this option over bromine, then you actually have a few choices to pick from. Most popular for tubs are sodium dichlor granules that dissolve quickly and are basically pH neutral so you don’t have to worry about affecting pH levels.

Bromine, on the other hand, ionizes contaminants. Bromine produces less of a chemical smell than chlorine. However, the smell it does have tends to be harder to wash off after you get out of a pool or hot tub treated with bromine.

Sensitive skin or respiratory issues? Bromine is probably the better option.
