only 3 MH over 8' tank ?

[bullitr]

i am currently using 4 MH with lumenarch mini on my 300 but i want to upgrade to 400 with 36" wide. the tank will have 1 large overflow on each side of the tank so the tank will be about 7" long and with 2 crossbraced it will be perfect . will the light covered most of the tank?

I have a 450 with the same dimensions, and I am using 3 400 watt MH in Large Lumenbright reflectors. Looks great~

You can also add some VHO OR T5 for supplments.
