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?

The one in the jar? I think.

but it's just a silly little 5 watt christmas light, it would hardly be bright enough to grow algae.
The correct answer would be the frag directly under the 250watt light, it doesn't matter how much water is surrounding it

Kind of suspected that too.
