    Do I need to shock ?

    I got a lot of leaves and twigs in my pool from the storm. My chlorine is at or close to 0 right now and has been for the past 2 days. Do I need to shock ?
    My pool looks relatively clear.

    If in doubt, raise you FC up (preferably towards shock level) and try an OCLT.

The SLAM process is not finished until: 1. CC < 0.5 ppm, 2. An OCLT < 1.0 ppm and, 3. The water is crystal clear.

    Sorry about that, Overnight Chlorine Loss Test. See:http://www.troublefreepool.com/pool-...rnight_fc_test. I would get your chlorine level up towards shock level before doing the OCLT.
