I suggest that watts of LED per gallon is not a good tool to use.

The reason is that there are many LEDs that use the same amount of watts but produce vastly different output.

I agree with RobbiG

RobbiG is right on target about finding out the needs of your corals and then buying what you need to buy in terms of equipment. Look up Dana Riddle's literature and that will help.
