One of the most important things to get right in a hot tub is the water.  Failing to use the correct chemicals at the right dosage could be extremely harmful to any users of the hot tub which is definitely something you want to avoid at all costs. 

Most commonly, people use Chlorine as their chosen sanitizer, it's the one that everyone has heard of and is familiar with.  There is also however, Bromine as an alternative.  But which one should you choose?  What's the difference?

Firstly, why do we need to use chemicals such as Chlorine or Bromine in a hot tub?  Well, these chemicals are sanitizers which kill bacteria.  After all, a tub full of hot water is a breeding ground for lots of nasties which you definitely want to eliminate before bathing.  A hot tub should be a healthy, relaxing environment, providing that you look after the water correctly. 

So that brings us to deciding which sanitizer you should use.  Here is a very brief comparison between the two.  Of course, we provide fill chemical training for all of our customers. 


Ultimately both chemicals will effectively sanitize your hot tub water.  The main difference is that Chlorine is more reactive than Bromine and as a result, will kill bacteria more quickly.  For long-term use this makes no difference, it just takes slightly longer for Bromine to take effect after an initial fill.  


Generally Chlorine dissipates more quickly than Bromine, meaning it needs to be replaced more often.  However, it's important to note that UV light destroys Bromine more quickly than Chlorine so during the Summer, it's extra important to check your sanitizer levels more often and replace your cover when your hot tub is not in use. 


Whichever chemical you choose, it's paramount that the dosage is correct for the size of your hot tub.  You will need more Bromine than Chlorine to sanitize the same amount of water although the argument is you won't need to top it up as often.  As mentioned above though, this goes out of the window during sunny periods.


As long as these chemicals are used in the correct amounts, they are both perfectly safe.  However, sometimes people can react differently.  For example, Chlorine in the humid air around a hot tub can irritate people with respiratory conditions such as asthma.  Chlorine can be harsh on the skin, eyes and hair too.  If you suffer from particularly sensitive skin, you may want to consider Bromine as it is gentler. 

Regardless of whether Chlorine or Bromine is your sanitizer of choice, make sure you read the dosage on the packaging and regularly check your chemical levels.  This will ensure that you always have a healthy hot tub!  In addition to the full chemical training and chemical starter pack you receive after your initial hot tub install, we're always happy to answer any questions you may have about caring for your hot tub.
