I got 2 ai blue over a 75g at over 1 ft. I still find the white intense and has bleached sps at 65% white, most sps is under 6-8" of water and Lps at the bottom.  
 
My lighting period is: 
 
3am to 3pm W-0 B-2 RB-3 lunar cycle on 
3pm to 5pm W-12 B-18 RB-24 45 min ramp 
5-7 w-20 b-28 RB-34 45 min ramp 
7-10 w-45 b-68 RB-76 90 min ramp 
10-12am w-25 b-30 RB-40 45 min ramp 
12-2am w-8 RB-18 45 min ramp 
2-3am w-0 b-2 RB-3 30 min ramp 
 
Still dialing it in and may change the lenses to all 70% as bleaching is still around.... I also get indirect sunlight during the mornings to afternoon through a few windows to the right side of the tank. 
 
I recently added 2 t5 for supplements with Fiji purple and they come on from 6pm to 12 am to see what kind of colors my sps and montis will have.....
