So, I have a green clear pool with algae. Using the K2006 kit I just got I have the following chem levels:
FC = 4.4
PH = 7.8
TA = 110
CH = 130
CYA = 45
Salt = 2900
From what I read in pool school I need to shock to 18. I know I need to lower the PH to 7.2 before adding chlorine. I know muriatic acid is recommended but is it ok to use dry acid?
I'm confused with the pool calculator. If I enter 18 as my target it says I need about 10L of 12.5% bleach to get to this level, but at the bottom it says adding that amount (10000ml) will increase my fc by 27. Did i do something wrong?? which is correct?
