Here are my numbers over a week after opening.
FC 7.2
TC over 10.0
CC 2.8
pH 7.7
Hardness 310
Alkalinity 160
CYA 40
I have been trying to restudy pool school and see if the pool lady's advice adds up. Her results indicated that I needed to add 3 more lbs of dichlor shock. She said that was because my combined chlorine is too high. I am having a hard time getting my mind wrapped around that idea, considering my Free Chlorine and Total Chlorine numbers are both hi. Can someone help explain?
