So, every day I come home to this. I run the dolphin and it's gone, but tomorrow after work it will be back. I've SLAMmed. Yesterday FC was 11.5 at around 2PM. Today its 9 at noon, so I think had I done the test yesterday after dark and this AM before sunrise it would have been in the 1ppm OCLT area. What should I do? I'm using the BBC method.
