I finally got my 150 up and running about 2 weeks ago and added my fish a week ago(moved filter from established tank to the new tank). I don't really have any good lighting for the tank yet and would like some opinions. I'd like the tank to be lightly planted so would need lights that would support things like java fern and some kind of moss. Also the tank is 72" and the openings are about 34" on each side. Would it be a better idea to go with 30" lights of 36" lights? Thanks in advance guys
