How about giving us all the chemical numbers?

CC
pH
T/A
CYA

FC, CC and CYA are the biggies since that's what you are having troubles with.

As I said I've got 2 3" tri-chlor pucks in a floater, and I added half of a 3/4 gallon 6% bleach bottle this morning at 7 am. I had fc = 1 and tc = 1 at the time ...

Readings at 6:45 pm

fc 0
tc 0
ph 7.5
al 100
ch 120
cya less than 30, probably 0 ...
