Chlorine Vs. Bromine System

Your hot tub is ready to go, but perhaps you’re confused about which chemicals you should use to keep your spa water clean and clear.

That’s perfectly normal, because after all, there are a lot of choices out there. With regards to your spa sanitation, two of those choices are chlorine and bromine.

In this article we look at the pros and cons of each. Let’s decode the chlorine vs. bromine system.

What is Chlorine, and What is Bromine?

Both chemicals can clean and sanitize your spa, but they do it in different ways.

They are chemical compounds capable of killing bacteria and germs that often grow in hot tub water.

Chlorine oxidizes any contaminants in the water. Your filter collects these and burns them away when you use shock. Bromine, ionizes any contaminants, and they are then removed in much the same way as chlorine.

Deciding which one to use is up to you. To help you with the decision, let’s look at the pros and cons of each.

The Pros and Cons of Chlorine

Chlorine is one of the most cost effective and fastest acting sanitizers you can purchase for your hot tub.

If you are looking to clean you hot tub quickly, and you don’t want to spend too much on maintenance, then chlorine is the way to go.

It isn’t broken down as fast by the sun as bromine if you add stabilizer to the water. Since most hot tubs aren’t necessarily in direct sunlight all day, this may not be an issue for you.

Chlorine has a high pH value to it. This means you must watch the water balance if you regularly use chlorine. Chlorine can also cause irritation to people with sensitive skin, and it has a pretty potent chemical smell.

The Pros and Cons of Bromine

While bromine may be a bit more expensive and a little slower to react than chlorine, overall it does a much better job of killing algae, bacteria and other contaminants for a much longer time. This is especially true in warm water environments like your spa or hot tub.

It does a really good job destroying bacteria and viruses.

The pH value of bromine is much lower than chlorine. This means you won’t have the chemical balance issues that you get when you use chlorine. Unlike chlorine, it doesn’t have as strong of a chemical smell.

Bromine is more expensive so your maintenance costs will go up. It can be hard to completely wash off your skin in a shower after you have spent some time in your hot tub.

Although it can cause skin irritation, it is usually much easier on your skin compared to chlorine.

Which Should You Choose?

Both chlorine and bromine are efficient at what they do. Both sanitize your spa and keep your water clean.

However, every hot tub owner is different, and you may have your own personal preferences.

If you forget to regularly add sanitizer to your hot tub or if you want to try and save a little money on maintenance, chlorine may be the way to go. However, if you have sensitive skin, bromine may be the better choice.

Special Note

Whatever you do, do not mix the two. Mixing bromine and chlorine together can lead to a very dangerous chemical reaction, so if you decide you want to switch, you have to change out everything and flush your system to remove any remaining sanitizer.

Final Thoughts

Both chlorine and bromine can sanitize your hot tub. Which one you choose is largely up to you.

Remember, no matter which sanitizer you ultimately choose to use on a regular basis, make sure you stick with it and clean your hot tub regularly.

Crystal clear, clean water can be yours for many years of enjoyment for your family and friends.
