To figure out how many watts per gallon I just divide my light wattage by the tank size right? so if I have a 265 watt power compact I divide that by 75 gallon to get 3.53 watts per gallon,yes?

Correct.

Correct, but you must realize that using the "watts/gal" rule for lighting is not a good way to go. The type of lighting will change things dramatically.

the wattage of the bulb will be the same if you are 3 inches from the bulb or 3 miles from the bulb. lumens and lux are used to describe the "brightness" and "intensity" of the bulb.
the watts per gallon rating is only a starting point for selecting a bulb. you really need to have a lighting system with enough "penetrating power" to get the proper amount of light (lux) for the depth of your tank. notice i said lighting system... not bulb. there are several things like distance from the bulb, type of bulb used, reflector design... etc.

Mp3.......so how would you determine the Lux needed at the bottom of a 24 inch high tank in order to grow a "high light" plant type?
