Haven't used pool for a couple of days. We've had some rain, and to be honest I haven't put any chlorine in since Thursday. Here are my results:

FC: 1.4
CC: 0.8 (I never have CC)
pH: 7.4
TA: 80
CYA: 30-35ish

Although I don't see any green, the CC tells me it's fighting off something right? Do I need to shock or just bring it back up to normal levels?
