This is our 2nd summer -we are new pool owners, and last year things went smoothly.
This year . . . .
Today's testing shows:
FC 1.5 ppm
CCl 0.5 ppm
Total Alkalinity - 220 ppm total alk. as Cal Carb.
Ca Hardness - 230 ppm as Cal Carb.
Cy Acid - too low to be measured
I am confused about the shocking. . .
1. Do I really want to add enough Chlorine to get to FC=24 ppm. . .
2. What is my best source for Chlorine - we bought some powder kind - it is Calcium Hypochlorite (and I see on this site that this could inc. my Calcium Hardness. . . )
any HELP very! appreciated
