Euglena invading algae sample - Percy priest Lake sample - PPL11102016 video

Euglena invading sample - AGAIN. This seems to be across the board on all my samples - starting to suspect unfiltered air supply...

These videos show a continuation of an invasion of euglena??
This sample clearly shows euglena invasion and almost wiped out other species....
