Pool Store Test Results

[Watermom]

It can take up to a week or so for all of it to dissolve.

Do I need to leave the pump running the whole time or just make sure I don't backwash it?

[CarlD]

Just don't backwash. You don't need to run the pump.

But you do need to get your FC up to shock levels to get rid of that CC. I believe 15 is the FC you need. Then you should be just fine.

Here is a new test.

FC 1.9
TC 2.0
CC 0.1
TA 118
pH 7.8
CYA 45

My question is:
When do you need to shock a pool?
When ever there is a trace of CC?
THANKS!
