Sure thing.
Is this for the bird's nest, or for multiple corals? If for the bird's nest, typically these are placed near the top of the rock work where the light is stronger and should have medium to high flow across it. You can tell if it's getting too much flow by watching the polyps. If they are not extending on the side facing the pump, then it's likely too strong.
For other corals it all depends on what they are, your lighting, and water flow management (wave makers, powerheads etc.) in the tank.
