I took this sample from the very bottom of the water jar. I think here is the biggest variety of protists. There really is a variety of life here from bacteria-sized to average-size. The strangest thing about this jar is that no biofilm was formed. The water flows freely throughout, even though the biome had been active for several weeks.
