Chlorine Vs. Bromine - Hot Tub Sanitizer Options
Chlorine or bromine - which is the best sanitizing chemical to use in your hot tub? What other options do you have? To answer that question, it will depend on your hot tub needs. This guide will help you weigh your options and pick the sanitizer best for you, hot hot tub, and your skin.
First of all, what is the difference between chlorine and bromine? Chlorine and bromine are both popular sanitizer options that are commonly used to get rid of bacteria or viruses in your hot tub or pool. So how do you know which one is right for you? Let's break down each chemical a little further and the pros and cons of each.
You may be familiar with chlorine as it relates to swimming pools, but the truth is, putting chlorine in your hot tub is just as important. In both cases, chlorine is a form of sanitizer that is used to control the bacteria that is in your hot tub or pool water.
Pros: Chlorine is the most common spa sanitizer. It's more cost-effective, easy to manage and apply, & effectively kills bacteria and algae through oxidization.
Cons: Chlorine can have a strong smell and can feel harsh to those with sensitive skin. It will also require more frequent water treatments compared to bromine.
Pros: Bromine tends to be better at killing bacteria and viruses, produces a lower chemical smell, is less irritable on the skin, and has a lower pH than chlorine which makes water balancing easier. Unlike chlorine, bromine doesn't oxidize. Instead, bromine ionizes the contaminants. Bromine is available in both tablet and granular form.The tablets can be used in a floating bromine feeder to help simplify spa sanitizing.
Cons: Bromine is a bit more expensive than chlorine. It does last longer than chlorine though, thus requiring fewer water treatments. Bromine also works more slowly, so it takes longer to kill bacteria. Bromine is also un-stabilized, so when exposed to sunlight it will burn off quickly. For that reason, it is recommended for indoor hot tubs or those that are not regularly exposed to a lot of direct sunlight. Bromine cannot be stabilized the way chlorine can.
What other sanitizer options do you have besides chlorine and bromine?
Alternative hot tub sanitizer options
There are some alternatives to chlorine and bromine as well as methods to reduce the amount of chemicals used. If you are trying to avoid chlorine and bromine altogether, there are alternative sanitizers that may better fit your needs. Biguanide is an effective sanitizer that is gentle on the skin and doesn't have the chlorine smell. There are also products that allow you to maintain a lower level of sanitizer, these could be physical products like UV bulbs and ozonators or it could be additional mineral or silver sticks.
So which one is better?
Choosing which sanitizer works best in your spa will depend on your specific needs & priorities. Factors such as how frequently your spa is used, your budget, and the time that will be spent on maintenance.

Can you use your hot tub without chemicals altogether?
No, unless you plan to drain your hot tub after each use as you would a bathtub, it is dangerous to use your spa without chemicals. The water sitting in your hot tub will be a perfect place for bacteria to grow. Not only will your water quickly lose it's sparkling clear appearance, but it could also actually make you and your family sick to soak in the contaminated water. Chemicals are used to keep your hot tub safe for use. Sanitizers such as chlorine and bromine kill the bacteria and keep the water safe to soak in. While the name "chemical" might sound scary, when used safely and correctly, they are your friends.
