Good! That means I was right to think that the green is the living/dying algea and the gray kind that settles in the barley straw must be the dead outer membrane of the plankton.
UNFORTUNATELY I'm out of brand new aqua filter and am using cleaned ones, but at least they were prior to the green abundance.
Okay so my list is septic stuff, plants, small pool filter, aqua mat sold locally.It just doesn't come easy I guess!
