Not to be insulting or anything but seems like a little bit of common sense. 
I feel that a majority of people overkill their lighting systems. The 
coloration and exapansion is related to the intensity of lighting and how 
much energy the zooxanthellae is getting. With less light, the corals will 
expand more to increase the surface area of tissue that contains 
zooxanthellae. Water current will reduce expansion on some corals such as 
lps. The coloration of corals is because of the chlorophyll contained within 
the zooxanthellae or uv protection pigments. With less light each cell of 
zooxanthellae is contributing a lower amount of energy. So if the corals are 
recieving alot of light, they can get away with lower population density of 
zooxanthellae which is what i think causes the washed out colors. When the 
light has been reduced, to achieve the same amount of energy they need to 
increase the population of zooxanthellae. Granted this is a theory of my own 
and am far from an expert. I feel there is a fine line between the perfect 
mix of light intensity and too much intensity. The perfect balance would 
produce corals with excellent coloration and expansion. Dont quote me on 
this, it has just been an observation of mine as iv moved different corals 
from different types of lighting, and as far as iv seen, I have nicer looking 
corals with less then recommended lighting.
