Powerhead help - MP40's or MP60?

[MrsReefK]

Hey guys, need your help on PH's. Tank is not setup yet, still in process of building our fish room. Tank specs below:

Acrylic hex flat back 290 DT
8' long
Return pumps will be turning about 1800 GPH that can be pointed where needed from 2 3/4" lines.

We have 2 Ecotech wireless quiet drive MP40's, looking to see if we should purchase two more, or possibly 1 MP60?

What do you guys suggest?

Either two MP-60 on opposite sides of the tank or four MP-40's. I would lean towards 4 MP-40's for better localized control.

Great, I was leaning towards the 4 40's as well for more options.
