My CC is at 1 and I was told to add a non-chlorine shock oxidizer called "shock and swim." How serious is a high cc? I have noticed that the FC is going fast. My CYA is at 30. My pH and TA are fine. Water is clear.
I have a little bit of muck at bottom of pool that I haven't vacuumed out yet. Water is too cold to get into. If I use the oxidizer, will that help with the FC?
