How often should I test my swimming pool water?

Swimming pool water testing should be done at least once a week, or after a heavy bather load or after bad weather. 

How do I regulate the PH in my swimming pool water?

To regulate the PH in swimming pool water either PH plus (sodium carbonate) or PH minus (dry acid) should be added. For dosing rates follow this link

How do I regulate the alkalinity in my swimming pool water?

Alkalinity can be regulated by adding alkalinity plus (sodium bicarbonate) or alkalinity reducer (dry acid). For alkalinity dosing rates follow this link.

Why does my swimming pool water smell?
