We don't understand Suggested FC Levels on the Pool Calculator.
I'm not sure which problem to address first...
our numbers for tonight...FC - 2.5
CC - .5
TC - 3
PH - 7.5
TA - 160
CH - 190
CYA - 40
Temp - 82
We, of course know we have chlorine to add tonight. But should we shock???? And if so, how do we figure out how much chlorine to add?
P.S. We've added 9 oz. of Muriatic Acid for the last two nights. jenn
