I just got a new sample in the time you responded to this. My filter/pump has been running a couple hours now where it wasn't before maybe that's the difference. I'm getting some pink now...it's pale but it's pink. 2 drops of R0871 turn it back to clear so that would put my FC level at 0.4? Then 5 drops of R003 to get it pink again, then 3 drops of R0871 back to clear. So 0.6CC?

Does this sound right?
