A swimming pool is essentially a contained living body of water which, if not balanced, chemically maintained and filtered, will eventually turn stagnant (usually up to 14 days).

Stagnant water is green, cloudy and will have a possible unpleasant odour, this 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:
–  Algae
–  Bathers
–  Extreme Weather
–  Filtration.


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.

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.

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.

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.


BLU52 offers pool owners Easy Test Strips to test for Chlorine, pH, Alkalinity and Cyanuric Acid.

  • The level of pH in a pool should be between 6.8 and 7.4
  • pH refers to the intensity of acid and alkaline materials in the water
  • Total Alkalinity (TA) measures the amount of alkaline substances (carbonates & bicarbonates)
  • Alkaline substances buffer the water against sudden changes in the pH of water
  • Total Alkalinity ideal range should be between 80 and 120ppm (parts per million)


Your pool filter must run for 6 – 8 hours daily. This will ensure clarity, cleanliness and efficient circulation of pool chemicals at all times.

Be sure to replace the pools filter sand at least every two years to ensure effective filtering of water.

A backwash must be done weekly regardless of the size of the pool and be sure to backwash for a sufficient period of time.

This will clean and expel all dirt, trapped debris and dust, maintaining clean and clear quality of water. Use the visible glass tube on the pump valve selector to check the clarity of water before ending the backwash cycle.

Following each backwash, a 20 second rinse is required to ensure that sand in the pipes do not circulate back into the swimming pool. Rinsing will skim and expel further dirt, trapped debris and dust from the filter, maintaining clean and clear quality of water.

Ensure that the automatic pool cleaner is unplugged when backwashing and rinsing to ensure that sufficient water is introduced into the pipe system and that no strain is put on the pump / motor.

Waste must be used when vacuuming debris off the bottom of the pool to ensure that debris is expelled from the entire system and not put back into circulation.

It is best to use a vacuum attachment that attaches to the net pole as this does not disturb debris like an automatic pool cleaner does. During manual vacuuming, be sure to leave the pump on “Waste” to expel debris and impurities lying at the bottom of the pool. This will ensure the debris and impurities avoid circulating back through the system into the pool.

BLU52 contains a flocculent to improve filtration; the product will attach itself to algae and unwanted debris will sink to the bottom of the pool, making it easier to vacuum.

Empty the catchment basket weekly to ensure that the water flows from the filter and into the pump and pool easily. A blockage will limit the efficacy of the filter/pump action, and once removed, lowers the possibility of water turning green by removing any leaves or debris that may land in the catchment basket.

Maintain your swimming pool during winter. This will prevent problems occurring when the summer season starts.
