Color changes in SPS due to Lighting Spectrum.

The color spectrum plays an important role in coral coloration. Different kelvin bulbs will change the way corals color up. Certain sps are from different levels of the reef (deepwater acros, shallow fringe reef sps and so on). They are used to differnet spectrums from the sun due to the saturation of light through water. But different wattages of the same kelvin bulb will give you different results. A 175W 20k bulb has a different PAR rating than a 1000W 20k bulbs. Here is where intensity comes in.
