I have a 40g half moon that’s 27” high. I’ve been messing with my light trying to find the right setting I really like the look of lights on blue 70% and whites barely on 9.5” off the waterline But nems wasn’t coming out. So I moved the light 16” or so off water line and turned blues on 100 and white on a little more and have a little more out of my nems today. What’s the best hight and setting for a tank as tall as mine. Oh the bb I use is the 165w
