Hi. I have the start of algae on my pool walls. I shocked the other day, but it is coming back. After reading your site I realize it is a process not a 1-time thing. I was wondering how I know if my FC is up to shock level (12)? My Taylor test kit only shows up to 5. Should I just go ahead and shock it twice a day until any sign of algae is gone & doesn't come back? Or if the overnight FC loss test doesn't show loss?
Thanks - Kathy
FC = 5 (I had shocked once)
pH = 7.4
TA = 115
CYA = 30
