Okay, pretty sure this is coralline that has algae on top of it or something. Maybe it is another type of macro because it does grow on the glass and starts as dark green? Where I have scrubbed the glass with mag float and it rubbed the back glass, it looks like a light gray/white maybe purplish underneath. Maybe you can tell in pic.
