Check chlorine level in pool water at least daily with a pool testing set and add this product as needed to maintain 0.6 to 1.0 ppm available chlorine. One pint of Clorox Bleach-Regular Scent per 6,000 gallons of water will supply approximately 1.0 ppm available chlorine.
Shock Your Pool. While under normal conditions you want to be sure you keep your chlorine levels at around 1 -3 ppm, you should also shock your pool to be sure you kill off any bacteria or algae that might grow. How often you do this depends on the area in which you live and how often you use the pool. At a minimum you should shock your pool every month but if you get a lot of rain or it is especially hot you may want to consider shocking it every week or every two weeks.
