need help with flow in my 120g

[rarelyseen]

I am getting ready to set up my 120-gal AGA. I need help with water flow in the tank. I am trying to decide which would be better: One Tunze 6100 mounted on a WavySea in between the two overflows in the center of the tank or Two 6000's mounted on either end of the tank with a multi-controller. Any opinions????

I would get the 6000's. Two 6100 is too much if you plan to have sand or non SPS corals.
