lighting for a 150 gal

MMM do you have a budget? are you aiming for a high tech or low tech set up?

high tech will be running co2, will have 2 fx5's 1 at each end, btw its a 150 long 72inch ecco complete substrate looking to spend no more than $500

If you want high light I would suggest Ray2 by Finnex, I have one on my 60 tall (24"). It puts anywhere from 60-80 at the substrate which is about 20 inches from the light..

Ray 2s will not work very well for a 72" 150g unless you get about 4 of them. I would suggest BML X2 or a comparable T5HO setup.
