Short in my fixture from spitting fish...

hardly, would not be adding up like that.

depth has more to do with anything then full volume. thats why watts per gallon is pretty useless as a measurement.

my tank is 3' long and 8" deep, I can grow just about anything without worrying about depth. If this light was say over a 40 breeder which is twice as high, would you be growing sps on the bottom of the tank? by growing I mean thriving, not just living.
