Just ran first full test after slam:

FC 6
CC 0
PH 7.5
TA 80
CH 100
CYA 30
CSI -0.62
TEMP 77
Looks like the numbers are all okay - but the CSI is in the red and I'm not sure if I should be worried about it?

Rest easy. Your vinyl liner is not affected. You can let your pH rise a bit and water temp will also raise CSI. Play with Pool Math and note the changes.
