Ok check this link out... I can't seem to get rid of this fuzzy
looking, red-brown, almost purple looking algae. Please let me know
if you know what this is or how to get rid of it... I've got 2 pics
here. I get it mostly on my powerhead but it gets on my water sprite
and my bananna plants and starting on my dwarf hair grass.
