you mean the purple coralin algae wont grow if i dont have reef lighting? i did not know that at all! i got some 50/50 lights and dont plan on growing any corals so does that mean that the purple up is just useless?

its brown, diatoms? i guess there is a silica problem in my tank according to what i have been reading...
