tank overflows
 

I am just getting a 180gal tank made and wanted to know where to put the overflows. Should they be in the corners or in the middle of the back. I am not putting in a closed loop but do plan to use a tunze wave box and some powerheads.

Wavebox? Get external overflows. Externals are better anyway if you have the room, but they are a must with a wavebox because you'll need a straight shot across the back of the tank.
