doubt its
coralline i have only had the tank up for 4 weeks and i have alot of this green algae. havent seen anything else. the
diatom bloom is just starting to go away from a few days ago. though i am surprised since i used tap water to fill because i couldnt figure out how to install my rodi unit. but i havent taken any of the rocks out of the water so how else would they bleach? too much light or too much flow other factors?
