You should see @florida_reef_keeper he runs 1 xr30G5 pro at 100% schedule and point intensity over his 40gallon with all the color channels at 100%! 100%!! he's got one of the best looking tank around imo. Im still slowly ramping up my two xr15G5 pros. Goal is 100%point intensity with the schedule at around 95-98% for me and all of my corals have already become a ton more vibrant.
