Shock needed for pool opening

May 28, 2014
Hi, I'm in my 2nd yearr of trouble free pool and just opened today. FC = 4; CC = 0; PH = 7.6; TA = 80 & CYA = 50. This seems to be where I settled out last year. I did bring up to shock when I closed and other numbers good My FC was 11 or so when I closed up last fall. My water looks good but I am curious if I need to bring Chlorine up to shock level or do I just adjust and go forward from hear. Any advice would be appreciated!
