The smell of chlorine around a pool is usually accompanied by irritation to the eyes, nose, lungs and skin of the swimmers. The pool smell is not due to chlorine but to chloramines, chemical compounds that build up in pool water when there is not enough free chlorine.

1. Brush the walls and floor of the swimming pool to remove as much of the algae as possible.

2. Ensure that the pH level is within the range of 7.2 - 7.6. This will ensure that any chlorine added will work more efficiently - high pH levels in particular will impair the efficiency of the chlorine doing its job.With the pool filter system running, add a chlorine based swimming pool shock at the rate of 1.6 kg. per 1,00,000 litres of pool water dosage for killing algae. The pool filter system should continue to run 24 hours a day.

During the cold winter months pool water tends to stay clear with very little help. Generally algae does not appear and hardly a pool turn green. If algae growth occurs, it  is extremely slow.

Of course winterizing is ideal, but many of our pools are not winterized. To these we add an occasional dose of chlorine and run the pump at least once a week. Vacuuming requirements are negligible.

1. Test the swimming pool water for Combined Chlorine, pH, Alkalinity and Calcium Hardness. pH and the Calcium Hardness are the main cause of cloudy pool water.

• To ensure accurate readings, replace test kit reagents annually.
• To ensure the highest water quality, test your pool's pH and free chlorine levels daily.
• Proper chemical usage is important for maintaining a healthy pool. Be sure to follow the chemical manufacturer's instructions closely regarding proper dosage for your size pool.
• Add an algaecide and chlorine to your pool before covering it for the winter. It will ensure that the water is clear and algae-free when you reopen it the following season.

Proper spa water maintenance requires using an effective sanitizer to control and prevent bacteria growth. No matter which sanitizing method you choose, spa water must contain a proper residual of bromine or chlorine, to keep the water safe and sanitary.

Since pool chlorine is available in different strengths, the type of chlorine one should choose will affect the amount required.  One's personal preferences and pool type might lead one to choosing type of pool chlorine above another.

Step by step procedure

• Firstly work out how much water your pool holds using this formula

(1 cubic metre = 1000 Litres or 4.5 Litres per 1 Gallon)

• Then Adjust your Ph Levels To a:

Minimum of 7.2
Optimum of 7.4
Maximum of 7.6

so 10g per 1000 litres per day of Ph plus or minus until you get a reading of 7.4

•  Adjust Algaecide levels

25ml per 1000 litres for initial dose then 2ml per 1000 litres every 2 weeks.

•  Adjust Chlorine levels

Initial Dose of chlorine is 6Grams per 1 Cubic Metre
Then 1.8g of Chlorine per 1 cubic metre when needed

Always have filter pump in operation when adding chemicals to pool and keep it running for at least half an hour afterwards.
