Thank you both George Booth and Ron Wozniak for your helpful information
regarding light intensity and water depth.  This information was most useful.

One other question.  If depth is not important, then why are salt water/reef
aquariasts concerned with depth and what type of lighting they use to 
"insure sufficient lighting reaches the bottom"??  Is it perhaps that certain
type of lighting are better at penetrating obstacles in a tank than others, 
since our tanks are not empty?

I have read that unless salt water/reef aquariasts are using a fairly shallow
tank, then they use more intense lighting (e.g. Metal Halide, Mercury Vapor?)
to reach the inhabitants of the tank.

Thanks,
