Thanks guys. I really like the cabinet setup too. The fixture came from my reef. It's a 4 x 54W T5HO 48" Wavepoint. It was on my reef, and it had an issue with the wiring for one of the ballasts and an end cap. The cap melted, and I couldn't risk waiting for a replacement, so I bought a 6 bulb fixture for the reef. I still have to replace the end cap, and fix the ballast wiring (which I thought I did already). Right now, it's just one actinic bulb, so that's why it's so blue.
