Why Pool Chlorine is Important

Many people ask “why pool chlorine is important?” Chlorine is used as the main sanitising agent in swimming pools.  Bacteria can grow in pool water due to a lack of sanitiser or poor circulation.

Bacteria then feed on any organic pollutants in the water.  As they eat the organic pollutants phosphates are left behind as a waste by-product.  Algae then use the phosphates as a great food source to thrive in the pool. Correct chlorine levels can limit bacteria and algae taking hold of your pool.

When chlorine is removing organic waste in the pool it gives off gases that create a strong chlorine smell.  When a pool is properly chlorinated, there is no perception of chlorine presence.  However, if chlorine is too high or too low eye, ear and nose irritations can occur.

A salt chlorinator makes chlorine very slowly and algae can grow very quickly so keep some good quality chlorine on hand at home for use after heavy rain or after a pool party.  Adding extra sanitiser to help your salt chlorinator can break the algae cycle before it has a chance to start.

Chlorine is the best defence against the bacteria and algae growth cycle occurring in your pool.  Keep the ideal level at 2-3ppm and you will have a very effective bactericide and sanitising agent constantly working for you.

More on Chlorine

As you learn your way around the pool you’ll appreciate chlorine’s importance in contributing to safe, clean water—making those visions of swimming in a sparkling, clear pool a reality.

Rule of Thumb

  • Always read and follow manufacturer’s instructions.
  • Store chemicals in a cool, dry and shaded place.
  • Never mix different types of chlorine — add each to the pool separately.
  • Never mix chemicals together — add each to the pool separately.
  • Avoid breathing fumes or vapours.
  • Make sure pool chemicals are inaccessible to children.

Tip to Save

Save on chemical costs by adding chlorine for shock treatment after dark — during the day some will be lost to sunlight.
