Do a 4 bulb T5 fixture. Do like 2 blue+/1 purple+/1aquablue special bulbs. Will be nice to look at, enhancing the blues, pinks/reds and at the same time lighting well the tank!
Price also is not bad, you can get a fixture for 200 bucks
John, how long is this tank?.. i have 2x48" Reef brights blue, all you need to buy is one white strip . with 1 white and 2 blue you can have nice color for FO tank, JMO
