Balanced pool water is the key to a healthy pool
TA, or total alkalinity is the most important indicator as it buffers pH, keeping it more stable. If TA is too low, pH will be erratic and “bounce”. If TA is in the correct range – 80 to 120ppm – pH will be stable.
pH is a measure of the acidity of the water. The pH scale goes from 0 to 14, where pH 7 is neutral. If the pH is above 7, the is alkaline; if it is below 7 the water is acid.
The optimum pH for pool water is 7.4, since this is the same as the pH in human eyes and mucous membranes. A pH of 7.4 also gives good chlorine disinfection.
“0.10ppm of chlorine is very effective in treating a pool when there are copper and silver ions present in the pool.” (University of Arizona)
How to make my pool clear and not cloudy
Another reason that your pool water may not be clear and blue is poor filtration. You need the correct size pump and filter combination for your pool size as shown below:
- 20 – 50 000 litre pool = 0.45KW pump with 2-bag filter
- 50 – 85 000 litre pool = 0.75KW pump with 3-bag filter
- 85 – 150 000 litre pool = 1.1KW pump with 4-bag filter
The filter sand traps dust, impurities, suntan lotion etc. Most of these impurities are removed during backwashing, but eventually the sand needs to be replaced, usually once a year.
