10 bulb powermodule or (2) 6 bulb sundials?

[rireuter]

i am starting to purchase equipment for a 175gallon 48x48x17 rimless build, and was wondering if a 10 bulb ATI would have enough coverage or if i should go with 2 6 bulb ATI's. I currently have a 2x250 MH w/ 4 t5 fixture that i am running on my 75, and want to go all t5.

Just get the 48" 12x54 watts Powermodule. it should cover prefectly and will look clean over that tank.

where are they selling the 12 bulb? i have only found 10 bulb powermodules.

I'm pretty sure the power module is a max of 10 bulbs as well. My vote would be 2 ATI sun power fixtures. ( 2 48" 6 bulbs) Then you will have 12 and better coverage
