Just need your opinion/suggestions. I currently have a single bulb 15 watt floresant strip light on my new 20 gallon tank. I am looking to purchase a double bulb strip light, and need your help on which bulbs to purchase. Im wanting either a white/blue-ish or white/pink-ish tint to the lighting, to enhance colors, but not be too bright...keeping the glow. Im assuming I should get the standard anticic white bulb, but what other bulb would you suggest to achive this look. Is it possible with the single strip light that I currently have?? Thanks in advance!
