I have shocked as directed by pool store over and over and gone through a $100 bucket of calcium chloride(? ) and still the FC level is 0.2-0.4. I have given up on the stores help and want to figure this out! Bought the test kit recommended here. I added one gallon of bleach and the next evening the FC level was the same.
FC - 0.4
CC - 0.4
PH - 7.4
Alk - 100
CA - 230
CYA - 67
My plan was to slam it, but the cc is under 0.5 so does it really need it? Water is clear I have seen a bit of green on the ladder steps no where else. I am having a graduation party at my house next Sunday and want to have the pool safe to swim in!
Also if I need to add lots of bleach do I add it all to the skimmer?
