Why Pools Need Chlorine

Chlorine is important for the health of any swimming pool. It acts as a sanitizer, killing harmful bacteria that can make swimmers sick.

Algae can make pool floors, sides and ladders slippery and dangerous. Chlorine eliminates this hazard.

Chlorine reduces the load on the pool filter by destroying organic materials in the water. This allows more efficient use of the filter and extends its life.

The Importance of Maintaining Proper Chlorine Level

Pool water needs the right balance of chlorine at all times to keep it sanitary. Too little chlorine in the water allows algae and bacteria to grow. Too much chlorine can cause health problems and can damage pool liners and metal parts.

Factors That Affect Chlorine Levels

It is more common that pools have chlorine levels that are too low rather than too high. Factors causing low chlorine levels include:

  • High water temperature.
  • Sunny hot weather.
  • More people using the pool.
  • Dirt and debris getting into the pool.

Testing And Maintaining Proper Chlorine Levels

To ensure proper chlorine levels, pool water should be tested once a week. It is important to maintain a chlorine level of 2.0-5.0 parts per million (ppm).

Test kits, test strips, or electronic testing equipment are available for home use. As an alternative, a water sample can be taken to a local pool store for testing.

Testing should always be done before adding any chemicals to the water. It takes time for the chemicals to do their work, so 24 hours should pass before retesting the water.
