Hi r2r’s... i have a decision to make and was wonder what are your thoughts... i have a deep blue 75g 48x18x20 sps dominant reef bare bottom... now i have both fixtures in hand.. ati 48x8bulb and 36x6bulb both non dim... which would you think is better ... 48x8bulb too much? Just right? Or 36x6bulb too less? Or good enough?... my lowest sps is at 5” and highest is at 12”

48", it's not too much. Running no more than 8-8.5 hours a day would be my suggestion. Start lower, like 6 hours, and work up. I ran that same light on my frag tank for years which was the same as yours, just shallower.
