Chad, I'm using the fast shutter option on my Powershot S40. I've got 4 lights turned on which brings out all the colors of the corals. The MH brings out the whites, the VHO brings out the blue/green, the 50/50 adds intensity and the halogen spot light brings out the yellow and adds lighting to areas in the shadows like where the sponges are.
The problem is that there is a lot of light contrast in the tank. The area below the branch rock is shaded while the sand area is fully exposed to light. So I think the reason why the sand turned up almost completely white has something to do with the camera letting more light in to get a good shot of the area under the branch rock. However, if it doesn't let in enough light, then the area under the tonga branch would be too dark.
