I have noticed my FCL has been almost zero on Monday and I start shocking my pool on Tue. Today my Lamotte Color Q shows FCL 5.2 but TCL is Hi or out of range. Question is, do I need to continue to shock my pool or is FCL of 5.2 good enough for now even though my CC got to be way up. I am using Ca Hypo to shock since CH is low and will tackle once I got my chlorine level stabilized.
Thanks in advance for the advice.
