Which Tank?

[fernalfer]

So i have the oppurtunity to setup a 120 gallon tank, problem is i have two. One is a single corner overflow and the other is a dual overflow with the overflows on the back wall.

Is their an advantage to having one over the other? If so which one would be best setting yp?

Mostly, its aesthetics, unless you pipe the dual overflow separately. Then you can have more flow through your sump. You could also do something fancy like pipe one to the refugium and other to the skimmer. The only real benefit is that the 2 overflows can help create less dead spots. Ultimately, it's what you like. Personallly, I really like the balance of the 2 overflows.
