What Are The Differences Between Chlorine & Bromine?

What Are The Differences Between Chlorine & Bromine?

When people purchase Hot Tubs, they know they’re getting a high-quality product. In order to function correctly and protect users from nasties that can live in standing water, they do need chemicals in the form of chlorine or bromine. Not everyone is aware of the differences between the two chemicals, or which makes the best choice for them.  This helpful guide will help you understand the differences, and why both have an important part to play in sanitising the hot tub.


What is chlorine? 

To begin with, let’s take a look at chlorine, and what it is, as well as how it is used in a hot tub. Chlorine itself is an element in the periodic table and most commonly has been used as a way of keeping swimming pools clean and sanitary, because it can act as a disinfectant. Chlorine usually comes in the form of tablets or sticks and placed directly into the water to begin cleaning it. Once inside the water it breaks down relatively quickly and dissolves to start the sanitisation process. As the sanitisation process continues, the chlorine creates compounds which are called chloramines. These are formed by combining with either ammonia or nitrogen, and produces the common chlorine smell which is found in swimming pools, and now some hot tubs too.


What is bromine?

Bromine is another element from the periodic table and can be considered a counterpart to chlorine, because it is in the same group as chlorine, and sits right next to it on the table. Bromine has many uses, but in this case, is used primarily for water treatment. Bromine itself should not be utilised in a floating dispenser, as it will only dissolve when it is placed in a bromine feeder and has water pouring over it. It is much slower to dissolve than chlorine and is also much more stable when exposed to higher temperatures and pressure. Bromine is actually preferred with spas and hot tubs due to the fact that you need less of it in order to purify your hot tub, as it takes longer to dissolve. It is actually a more efficient method, so you’ll be saving money in the long term, because you won’t need to purchase large quantities of chlorine in order to regularly cleanse and purify your hot tub.

These are just a few of the differences between bromine and chlorine. Both elements have their merits and are each best suited to different tasks. For example, chlorine is best used in swimming pools on a large commercial scale, being able to quickly and easily clean and sanitise a pool, but some people feel more comfortable using it for their hot tub rather than bromine. That said, bromine is suggested for use in hot tubs in Nottingham or Derby, as it is a more cost-effective solution due to its slow rate of dissolving and it’s efficiency at cleaning hot tubs.
