No, I use one vial for C1 and a seperate vial for C2. I always point the 10mL label forward.

I found some better tips from Hanna Instruments here: http://www.reefcentral.com/forums/sh....php?t=1961215

The instructions say to shake for 2 minutes, but on the forum post it sounds like it's not required.


I'll try that tomorrow with the same cuvette. I did the test again and got 5ppb (6ppb and hour before that)
