Bromine: The alternative to chlorine

Join us for part three of our FAQ series, we’ll be going in-depth on bromine an excellent alternative option to chlorine.

Bromine is an effective sanitiser, it has its advantages and disadvantages and we will go over them with you so you can make an informed choice.

Advantages

More stable at high temperatures

Bromine easily dissolves in water, as does chlorine. Where bromine really shines is that it has a higher ‘gassing off’ temperature. It takes a temperature of 58.8 degrees C for bromine to become a gas and be released into the atmosphere. As this temperature is much higher than you’ll ever use in your hot tub, spa, or pool, it’s safe to say you won’t lose your bromine this way.

More potent at higher pH levels

This is important because of the high bather-to-water ratio in spas and hot tubs. The hot water causes the chemical reaction rates to increase and the free sanitiser is depleted much faster. Chlorine, unfortunately, has lowered sanitising power once your pH goes above 7.5; the effectiveness drops and you will see an increase in equipment corrosion.

Bromine can be reactivated by superchlorinating

When bromine does its job sanitising your pool, spa or hot tub water, it leaves behind bromide salts. You can reactivate these salts back into sanitising bromide by adding the correct amount of chlorine or non-chlorine shock (available in granules and tablets) to the water, this is also known as super chlorinating. This process allows you to use less bromine by reactivating what is already in your hot tub, spa or pool. Chlorine, on the other hand, becomes inert after sanitising.

Bromamines are still active sanitisers, with low odour

Bromamines are a byproduct of bromides reacting with water contaminates, just as chloramines are. The difference is bromamines are good sanitisers and cause no odour or irritation. You can also regenerate bromamines into bromides as you read in the advantage above.

Adds no cyanuric acid or calcium to the water

High levels of cyanuric acid, the chemical stabiliser used with chlorine, can cause water cloudiness and it binds with the chlorine lowering the sanitizing effectiveness. Whereas excess calcium can cause scale build up.

Less Bleaching of swimsuits or clothing

Chlorine used for sanitising becomes hypochlorite in the water, the same ingredient in bleach. This is what causes the fading/bleaching action in clothing and bathing suits. Bromine, does not have this ingredient. It will cause fading, but over a much longer time period.

Disadvantages

More expensive

Bromine products are more expensive that chlorine products, here at SpaChem chlorine products are 20% cheaper than bromine. The higher cost to purchase bromine can be off set by the fact that you actually use less of our bromine products to get the same sanitising power as chlorine!
