Another Data point to the ongoing theme that everyone's Dinos are not the same:
My amphidinium shows most prominently on the sand after hours of daylight, and largely disappears from the sand overnight. Like normal.
But running my skimmer all night through early morning, and looking at sample after sample in the microscope, I never see amphidinium, (nor my other Dinos I'm calling Coolia either, but they are less studied, and harder to find info on). So where the heck does it go when it leaves the sand?
Turns out some amphidinium species (Those that are laterally flattened, like mine) makes a daily cycle
within the sand going deeper at night.
So since I'm going for dirty/max competition then skimming is completely counterproductive, since it removes exclusively Dino competitors and no dinos.
That make sense other than just in my head?
