The amount of ph and chlorine levels should not vary by the number of users or their activities. A good chlorine level is between 1.0 and 4.0 parts per million (ppm), while the pH should be between 7.2 and 7.8. Together, they keep bad bacteria at bay: If pH goes up too high, chlorine's germ-killing power deflates. These levels should be tested everyday with a small chemical kit.
