Another Lighting Question

[twflint]

Greetings, Just a quick question regarding lighting.
I am running a 90 gallon tank with 50 lbs of live rock currently (will be adding more, will be building a reef tank) and using 2 175watt Metal Halides with 10000k bulbs. I have found a 48" 40watt flourescent that I am going to be putting into the the tank also.
I need some blue. The tank looks much to white. What bulb should I use in this type of flourescent fixture?
Thanks for everyones help.

I would go with an blue antinic bulb. I use the Coralife brand.

i doubt you will sen much blue with the 40 watt bulb. the halides will probably drown it out.

next time you buy bulbs you should try the 12 k bulbs. i use them and they are not too white and not too blue.

Thanks for the replies all. If I hadn't just dropped 150 bucks on the 10000k's I would get some 12k's. Just wanna try and get something that will augment the 10k's.
Thanks guys All!
