Just starting with the TFPC method for the first time, had to drain 50% and re-fill to get my CYA down. My chemistry was the following after the refill:
FC: 0.6
CC: 0.4
PH 7.5
TA: 70
CH: 220
CYA: 35
According to the calculator (8.25% bleach), I needed to add 1 gallon to push the FC up to 5ppm. I put a gallon in, ate dinner, etc. About an hour later I re-tested, FC was the same thing.
Am I not waiting long enough, or how long does it take before I will see results in my test?
