okay so when that happened I dumped 2 more bottle of bleach in just to be safe. I just went to check my FC and I ran out of drops at 16ppm , and it was lighly pink , so it seems the FC is still holding high. I ordered more reagent yesterday , so I won't be able to test my chlorine for a few days. I've been putting 1-2 bottles of 8.25 bleach in the morning , afternoon and evening and that has been holding it above shock level.
Should I continue to do that , until I can test again?
