Green polyp coral

[SirPug]

Ok I have two frags of green polyp coral one is darker in color and looks healther this one is in direct flow of one of my rio 1100 pumps. the other sits a little lower in tank and gets some water flow from my other rio 1100 pump but color is lighter and to me does not look as healthy. Does it need more water flow? Or am I seeing things and looking for problems where there are none?
TIA

I thought they liked Medium to low flow...
Maybe give it more light?

they both have the same wattage of light. I will check and see what the difference in my two MH bulbs are.
