Chlorine

Why do Swimming Pools Need Chlorine?

Chlorine is a naturally occurring chemical element. It is most commonly used in swimming pools as a swimming pool sanitiser, although it can be switched out with bromine.

Chlorine will help to keep your pool as clean as it can be by killing any nasty bacteria (such as that which leads to algae) as well as keeping your pool water crystal clear.

One of the most important aspects of swimming pool maintenance is ensuring that your swimming pool’s pH level is as balanced as it can be. This is achieved by treating the water with chemicals — such as chlorine — both regularly and by using more intense shock treatments when necessary.

How Often Should I add Chlorine to my Pool?

During the busiest seasons, you should aim to treat your swimming pool with a chlorine shock treatment once a week in order to keep it clean.

The best time to shock your pool is during the evening after you’ve cleaned all of the day’s debris out. This means the chlorine in your pool has plenty of time to work its magic without the impact of UV rays. Too much exposure to UV rays can break down the chlorine in your pool and weaken it until it’s no longer killing bacteria.

Other times you should shock your pool with a chlorine treatment are:

• When you open your pool for the season
  After heavy use (e.g. a pool party)
  After extended periods of hot and sunny weather
  After heavy rain
  When you close your pool for the winter.
