I have a Coralife Fixture that currently has (2) 10,000K Daylight and (2) True Actinic 03 Blue Compact Flourescent lamps in them. They are getting old and you can tell that the light is a lot dimmer than it used to be. Whenever I go to pet stores it always seems like the colors of those fish are so much more vibrant than my fish. What should I put in my Coralife Fixture that would showcase the fishes colors the best? I don't have any corals and was wondering what color temperature would work the best.
