Is it normal for Plankton to settle in 48 hrs?

[Seng]

Hi,

Had cultured several bottles of plankton (nano Strain). Have observed that the plankton will settle in ard 24 - 48 hrs time, leaving a distinct layer of clear water on top, and denser plankton below.

Is this normal?

Will appreciate any assistance. thanks

IMHO, yes. this is normal. as it is in DT. that's why the instuctions clearly states that u'll hv to shake the bottle every 2 to 3 days to keep the planktons suspended.
