Ok then look at it this way, If you took a gallon jar put some rock and salt water in there and placed a little frag 5" from the surface of the water and then hung a 5 watt christmas light over it the frag would be getting 5watts per gallon of light.
Now if you took a 500gallon tank, with rock and saltwater, frag 5" from surface and hung a 250watt light over it, you have 1/2 watt per gallon
Which frag is getting the better light?
