wattage per gallon is an ancient method that is of no use what-so-ever ... You can't compare 150w of t-5 to 150w of mh ... 2 completely different types of light ...
Mixed reef ... If you don't mind the heat i would personally go with mh ... Or a good 6-8 bulb t-5 fixture with individual reflectors ...
How deep is the tank? What size tank? Specs would help determine what you would need. :d
It's a 215 gal oceanic, 28" high, 2' wide and 6' long. I am currently running a coralife aquapro combo light. Not sure if this is sufficient.
