What do you guys recommend for a double end hqi bulb for acropora dominated system? I have only used MH briefly 5-6 years ago with ZERO direction. I recall using Phoenix bulbs, I think I ran 14 or 15k... probably not the most asthetically pleasing but definitely grew coral. I would like to find the deepest blue that I can (20-22k?). I assume you would still achieve a fairly balanced spectrum that will grow stonies but is pleasing to the eye. What do you run for bulbs on your sps tanks? Any and every experience is welcome. Oh the fixture is a dual 150w dual end hqi (300w) over 48”.
