A swimming pool is essentially a contained living body of water which, if not balanced, chemically maintained and filtered, will eventually (usually up to 14 days) turn stagnant (green, cloudy and with a possible unpleasant odour) and will allow for dangerous bacteria to thrive. This bacteria is the main cause of skin, nose and eye irritations. The four main factors that contribute or accelerate the rate at which a swimming pool turns stagnant and unhealthy, are:

  1. Algae – The most common method of introducing algae to your swimming pool is by wind. Algae spores are around us the whole time floating within the atmosphere. Algae will deposit itself within your pool and, providing conditions are conducive, will begin to multiply. Algae (black, mustard or green) will cause unsightly stains to your pool but more importantly will provide nutrients for bacteria to thrive on. The combination of algae and bacteria will cause the water to discolour – usually to green.
  2. Bathers – The average bather will introduce perspiration, body oils, suntan oils, urine and dirt into the swimming pool. If these are not chemically broken down they will contribute to your pool turning stagnant.
  3. Extreme Weather – Extreme weather conditions in the form of lightning, rain and prolonged heat spells, will alter the water balance (pH) of your pool which in turn limits the efficacy of all pool chemicals.
  4. Filtration – The most common swimming pool filtration system in SA is the sand filter. The filtration system (pump, motor and filter) circulates water through the filter sand removing dead algae, waste and debris. It also assists the distribution of chemicals in your pool water. To ensure that your pool water quality is kept at its best your pool filtration system needs to be serviced every two years.
