lighting requirements

[TANGOMAN]

Well I set up my first freshwater tank today. Ok, I've had 'em for years years but it was long ago...those of you who had stainless steel trim on their tanks know how long...
I'm going to talk with a local lighting supplier tomorrow for some supplies and I wanna' get some bulbs too. 4' fluorescents. I stole a couple of the wifes "plant/aquarium" bulbs but I'm not happy with the look. Too green. What kind of bulbs might I look for to obtain a "whiter" look ? Will I get "that look" if I request a 6500K bulb...
