    How long has your tank been up and running. Looks like it in the middle of a cycle...
    If the water is yellow you could run some carbon to clear it up. How long has it been yellow? Have you added anything to the water.

    I added Live Sand on Friday night with base rocks, then on Sat. I added like 12lbs of live rock. So three days :). I added 2 pieces of raw shrimp yesterday. It has been yellow since the water has cleared up. Like 1 day.

    I can leave it alone. I just want to make sure there isn't anything weird going on w/ yellow color.

    Thank you for your input :)

    The yellow tinge to your water is called Gelbstoff! It is an elevated level of dissolved organics. Carbon and a water change will help to reduce this from your water.
    This yellowing of your water, is detrimental since it diminished light attenuation. The PAR of your lighting reaching your tankmates below can be cut in half as a result of this Gelbstoff. Also, the blue light emitted from your lights is also reduced!

    i agree with carbon.also your water is warm.below 82 is prefered.a fan can bring it down a couple degrees easy.also bulbs below 10,000k without actinics can give a yellow look

    I agree with the carbon and get that water temp down as it is too high.
    What is your Calcium and Magnesium at?? Need to get your dKH up a bit too.
