Just received the T100 test kit (hooray) so now I have an accurate FC reading. Some background - have partially (70%) drained and refilled the pool twice this month due to very high CYA levels (bad advice at the pool store). Anyway, went to the BBB method with the help of this great site and pool is finally clear.
Unfortunately, I am still very high with CYA and shock level of FC hasn't gone down as much as I thought. Based on the results below, can I swim right now? We are in S. Florida and pool is heated to 85.
FC = 27
CC = .5
CYA = 90
PH = 7.2
