What bulbs in a 2x55w PC hood for a 15 gal nano

[geoffgarcia2]

K, you guys have all been super duper helpful so far in answering all my question! now
                     this is one of the last I have! *haha*

                     I'm getting a 2x55 PC fixture, and am trying to pick the bulbs, the choices are like
                     50/50, 6500, 10000k, and an acitnic. which do I choose!? (two different bulbs? two of
                     the same?)

                     This is for a 15 gallon by the way, I'm going to put 20lbs of live rock and put a 1-2"
                     sand bed in there also.

You are going to want the actinic and the 10000 k bulbs. It also depends on what you are going to keep in the tank. Also 4 key main factors for your tank; water motion, water chemistry, temperature, and lighting. Good Luck

I second a 10K and a true actinic.  Please make sure it says "true" actinic and not a blue bulb.
