I did the FAS-DPD Test twice this morning. According to it, my FC was 18.4.
This is not possible. My TC level was 0 according to an OTO Test, Test Strips, and the AquaChem TruTest Reader last night, and I added 3 gallons of 8.25% bleach which should have brought the chlorine level up to 16 ppm.
Additionally, my CYA is not measureable (I have been using Dichlor to supplement bleach additions so that I can raise it but it's not happening quickly enough, so I bought liquid stabilizer today), so I know that the chlorine SHOULD have dropped some based on the cute little piles of algae a the bottom of the pool a few hours after brushing.
Even after the 90+ drops of reagent, there still seemed to be a very slight pink tint to it but my wife says I was seeing things and I do have a difficult time seeing faint colors.
