    If I put 2 10,000K light together, do I still get only 10,000K of lighting or does it double the light??? [smiley=help.gif]

    You just get more watts; the Kelvin remains the same.
    Usually, 3-5 Watts per gallon is recommended for reef tanks, but the type of bulb (ie PC vs. VHO vs. NO) is most important.

    What that is some bad info.
    VHO = Very High Output
    NO = Normal Output

    VHO are kinda like fluorescents on steroids. You can grow a lot with these bulbs and they can have a dimmer switch timer thingy for smooth transitions. No glimmer lines like Halides though.

    NO bulbs are just fluorescents. Not much good for reef tanks unless you have a ton of them, even then you are restricted in what you can have.

    Yeah, 2 10k's does not equal a 20k.  It just means you have twice as much intensity in the same color spectrum.
