Yes it is spreading to most of the LR in the tank. Teresa, glad to hear i am not the only one with orange colored coraline.
This is in my 55 where i have T5's. My 150 has MH, T5 combo and i don't have any orange at all, though some of the LR that has the orange came from the MH tank, but it didn't start growing until i switched.
