Pool Store Test Results

[LFRoberts5]

These are the results I just got back from the Pool Store.

FC 2.4
TC 3.2
CC 0.8
TA 131
pH 7.6
CYA 47

This is after adding 4# of CYA and letting the pump run for about 4 days to let it all dissolve.
I have a 11,000 AG vinyl liner pool.
Any suggestions as to how the numbers look and what I should do?
THANKS!

Your numbers don't look bad, except that I would shock it to get rid of that CC. Also, I'm not so sure that your CYA has finished dissolving in the water--it wouldn't suprise me to see it increase a bit more. How does the water look?

Right now the water looks great!. How long do you think before all of the CYA is dissolved?

[Watermom]

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

[LFRoberts5]

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.

[LFRoberts5]

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!
