Nice to get that cover off and test!
So, I plan to go completely BBB this year and here are the test results after vacuuming and letting things circulate a few hours with about 3/4 of a gallon of 12.5 bleach.
FC = 10.5
CC = 0
TA = 80
CYA = 60
PH - 7.4
Is it possible that there is no CC here? The water is a bit cloudy, was clear upon opening but there was a bit of debris and a few spots of white powdery substance there.
We just added another gallon of 6% bleach to take it up to about 20 FC as per that great calculator and CYA chart found here. We think it is starting to get a little more clear......are we on the right track here??
