Why Use Hot Tub Chemicals?

The fact of the matter is, that temperature and humidity of hot tubs provide the perfect condition for bacteria growth. Germs and bacteria can build up as a result of the environment and also the regular traffic of people getting in and out of the water. Hot tubs are perfectly safe to use, but the chemical balance of your water is very important, the pH levels must be neutral and the sanitiser at the correct level throughout the hot tub.


Hot tub chemicals are all very similar, there is not one leading brand as such. It is always best to stick with the chemicals that your dealer uses as they will understand them and always be on hand to give you advice should you need it. You should be adding a hot tub sanitiser to your water (Chlorine or Bromine) to ensure that it is stays clean. You will be looking for a reading of 1-3ppm for Chlorine and 2-6ppm for Bromine. It is also important to balance the pH of the water, this should be between 7.2 and 7.4.

When used in the correct quantities, you should not experience any discomfort from hot tub chemicals. However, if you have too much chlorine or bromine in your spa, you might experience slight irritation of the skin, nose, and respiratory system. This is why experts recommend testing the water before every use to ensure that no problems will occur.
Hot tubs have the potential to become breeding grounds for bacteria and germs, which is why treating the water is essential to keeping your tub disinfected and sanitised. If you don’t add chemicals to your hot tub, you’ll rapidly find that the water can turn green and smell stagnant. This poses a significant risk to the safety of any users, so avoid using the hot tub if this happens and consult a professional on how to revive the spa.
Hot tubs will not last long if you do not use chemicals in them. It is important to use chemicals for your own safety, and conducting both a visual and chemical check will ensure everything is safe. Any discolouration, cloudiness, or a film on top of the water should be addressed.
