    Pump run time and testing

    I run my pump from about 7am to 7pm everyday and my numbers have been real good, pool crystal clear too. When I get up in the morning and turn pump on, I wait 30 minutes and then test. This morning I decided to test before turning pump on. My FC was 6 but my CC was 1. After running pump for 30 minutes, I retested and the CC was 0. Would this be normal with the pump being off for 12 hours?

    Re: Pump run time and testing

    Testing water that has been sitting still for hours will give different test results, so it is possible you hit a pocket of high CC, but when the water was mixed it dissipated to the lower value. When your pool is well circulated and you still test 1 CC, then you have a problem.
