I'm running SOL whites but I've replaced some of the pucks with sol blues so its sort of a mix...but I also run 6 Panorama Pros, which are not dimmable. I'm just trying to keep a balance that looks like my old tank (20k radium MHs). I think I may be setup a bit week on my lighting schedule, but with the 6 Panorama Pros I'm not sure how much I should be cranking the Sols. Maybe the Panoramas are not as strong as I am thinking and I should just friggin go for it with the Sols.
