How To Lower Bromine In A Hot Tub If The Level Is Too High (The 3 Easy Methods)

Although it is good to lower bromine in a hot tub when the level is high, don’t allow it to go below 3ppm when reducing it. The high amount of bromine or chlorine in your hot tub may help to kill all germs in the hot tub, but it’s not safe for your health.

So, anytime the bromine levels go beyond 5ppm, try your best to lower it. You can lower the bromine in your hot tub by diluting the water in your hot tub, using a bromine reducer/neutralizer, or by allowing the bromine to escape from the tub through evaporation.

My closest cousin enjoys spending her time in the hot tub, which I believe is a way of relaxation for her. But she complains a lot about having itchy eyes, skins, and other symptoms. This could be a result of the high level of bromine in the hot tub. Of course, having a good amount of bromine in a hot tub is great. Bromine is good for preventing dangerous and sickness-causing germs in a hot tub. It has a lesser odor than chlorine and also helps to keep the hot tub clean.

But having an excess amount of it in your hot tub is not safe for you. So, just like my cousin, you might have been having skin irritation lately and attributed it to other things maybe your cream or other cosmetics. Well, it might be the side effect of excess bromine in your hot tub.

So this piece is here to educate you on how to:

  • Detect when there’s so much bromine in your hot tub
  • The effect on you and your hot tub.
  • The importance of having the right bromine in your hot tub.
  • How to lower it, and lots more.

What is bromine?

Bromine can be described as a chemical element that is reddish-brown.  It is mostly used as a sanitizer in hot tubs and pools. It helps in stabilizing high temperatures and widens the pH range. It also helps to kill germs in the hot tub. But despite its good effects as stated, it can be hazardous when it isn’t used in its right proportion. 

Can bromine levels be too high?

Yes, bromine levels can be too high when it is above the recommended levels.  It can only be safe at a level between 3 – 5 ppm (parts per million). Any level more than this is too high and would become hazardous. The only way to ascertain this is by testing your hot tub water regularly to lower it for a more potent effect.

Causes of high bromine in a hot tub

Some of the factors that can cause high bromine in a hot tub are the presence of excess chloramines, pH imbalances, and copper in the hot tub water. Also, adding too much bromine to your hot tub could be the cause. So, it is better to have a test strip handy to test the level of bromine, especially when you are adding it to the water.

How to detect high bromine in a hot tub

The recommended level of bromine in your hot tub is between 3-5 ppm (parts per million). The bromine level is high if the test reads anything above 5ppm. It is an indication that the bromine in your hot tub is high. Follow these simple steps to test for bromine level in your hot tub:

  • First, read the instructions on the test strip pack.
  • Open the pack and pick one test strip.
  • Dip the test strip in your hot tub water for 2 seconds.
  • bring the test strip out of the water and flip to remove any excess water.
  • Then hold the test strip up to the color chart on the pack and know the level. It should not be above 6ppm or below 2ppm. But we recommend 4ppm. However, some test strips will show you the best position where the ideal level should be. Some will write “OK” on the mark.
