The only thing that changed was the nitrate. It spiked during moving the tank to 1ppm. After 3 weeks it had fully colored up. You're on the right track with your thinking. The lights have less to do with it than most people want to believe. I'm not saying you can color acro with a standard light bulb. I'm saying if it is adequate lighting for sps then that's all you need.
