New to BBB Method. Need some help.

Hi! These are my readings using the K2006:

FC 4.5
CC 2.0
PH 7.2
TA 90
CH 390
CYA 150

I am going to drain and refill to get the CYA down. Should I do that first or should I shock first to get the CC down?

Thank you!!!

My pool is AG 15300 Gallons

If you have an above-ground pool, drain only in increments. By doing too much at a time, you run the risk of getting wrinkles in your liner.

Thanks. I am draining only about 6 inches at a time. (Just to the bottom of the skimmer) I have drained about 21 inches so far, I am going to test again before I drain anymore.
