Would 8 bulbs be enough? Would that be more intense then the 2 x 400 mh? Is powermodule still the best light out there?
With an 8 bulb PM you don't need to worry about if you will have enough PAR. The PM will give you plenty of light in the tank. More bulbs don't equal more PAR, more bulbs gives you the same PAR but over a greater area.
I just wouldn't try to keep high light stuff on the sand at 31 inches.
