pH control is the method to determine the degree of acidity or alkalinity of your pool water. Do a colour comparison test using a Poolwise Water Test kit Neutral water has a pH factor of 7.0. A reading below this indicates the water is acidic and a reading above indicates the water is alkaline. 


For swimming pool the water should be 7.2 and 7.6, this is importantbecause clhorine is most active at this level and it can do the most effective job of controlling bacteria and algae. This also saves on chlorine usage.
