How to use bromine in your hot tub

There are several disinfection methods by chemical treatment: chlorine, bromine and active oxygen. Among these three methods, bromine has the distinct advantage of being persistent (it remains active for several days in a clean spa), being insensitive to pH and having practically no odour (or none at all).

Are you treating your spa with bromine or do you want to treat your spa with bromine? Here is some information that may help you.

After draining or restarting the spa

If you change the water or if your spa has been off for a while, it is possible that biofilm has developed in the piping. It is therefore necessary to start with a cleaning using the Ahh Some. The instructions for use of this product are given on the corresponding page.

Regular treatment

Now that everything is in order we can start. Once the spa is filled with water, here are the steps to follow:

Start by adding non-Chlorine Shock, at a rate of 15g per cubic meter of water. The latter will eliminate the bacteria present in the water.

Then add the bromine at the rate of two tablets permanently in the basket of your skimmer, or use the tablet diffuser that you have to fill with tablets, and adjust for a slow diffusion. To do this, refer to the instructions provided with the diffuser

It will also be necessary to add a dose of non-Chlorine Shock to eliminate bacteria, perspiration and other organic matter brought in by swimmers.

Ideally, you should check your free bromine level once a week, just before swimming. This rate must be between 2 and 6 ppm. Two methods of measuring the free bromine level are possible: with strips (fast, but imprecise) or with an test kit containing DPD1 tablets. We recommend the latter method instead.

"Shock" your water regularly

The use of shock is important, as bromine will act against bacteria each time the spa is used. But it will gradually become saturated (Free bromine will be less and less present, and there will be more and more combined bromine instead). We will therefore "release" it again by shocking the water with the chlorine-free shock.

Check the pH value

If bromine is not sensitive to the pH of your water, you still need to adjust it ideally to ensure good treatment stability. As a reminder, a good pH is between 7.0 and 7.6.

  • If the pH is too low you will have to usepH plus
  • If the pH is too high you will have to usepH minus

If you notice that the TAC (total alkalinity) of the spa is too low, add a little pH stabilizer.
