Be sure that the samples you remove are of the upper layer.

The last lab I worked at used phycob or c as a measurement for cell concentr-
tion. It works nicely, but you shouldn't forget that after breaking the cells,
or treating them with lysozime/EDTA, you should sample and add cold aceton to
a final 80% concentration. This will get the blues out of the cells.
Good luck,
