I'm sorry, my Confusion Alarm just went off. Could you go into more
detail on why FL light is different than MH light? Are the photons
Also, I know you didn't mean this, but what you said was that if a 30"
deep tank was lit with FL bulbs, the lower 14" would be pitch black.
I don't think this happens in real life.
