In ~18 years of reefing, I feel that I've always had good luck keeping SPS alive and growing, bu I've never been great at keeping them colorful. My current tank is my first SPS dominate tank (most all tanks before were LPS dominate tanks with some SPS frags). I'm curious what some of the 'old hats' have to say on the subject.

My current tank is a 45g 2' x 2' cube. I have a 150 S Octopus skimmer and I dose kalk with an osmolator. My lights are a 8 x 2'; ATI sunpower T5, with 4 blue+, 2 Coral plus, and 2 aqua blue special. Any thoughts on how I can improve results?
