Is chlorine a gas?
As bromine is at rest in the liquid state, it does not “gas off”. It stays in the water and continues to sanitize. On the other hand, chlorine’s natural state is a gas. It has a strong tendency to gas off and become airborne.
Does chlorine sanitize pool?
Chlorine also loses its ability to sanitize once it has combined with waste. Besides the expense, continually adding chlorine to your pool is a hassle. When the efficacy of bromine starts to lag, it just needs to be reactivated, so there is less work and less expense.
Is bromine better for pools?
As a result, bromine is often the better choice for indoor pools. 2 – Bromine retains its sanitizing efficacy – because chlorine reverts to a gaseous state, it also loses its potency. Chlorine-treated pools must be “shocked” with heavy doses of new chlorine to maintain the proper levels needed to keep the pool clean.
Is bromine the same as chlorine?
Despite the fact that bromine has been in use since the 1930s, its benefits have been overshadowed by its better known cousin, even though bromine offers unique benefits that chlorine cannot match. Bromine comes from the same chemical family as chlorine, and is also capable of attacking microorganisms to clean the water.
Is bromine a liquid or solid?
Here are five things that you should know about bromine when you are deciding on which type of pool sanitizer to use: 1 – Bromine has less odour than chlorine – in its natural state, bromine is a liquid. It is found naturally at high levels in seawater. As bromine is at rest in the liquid state, it does not “gas off”.
