Overflow Placement

[coryjac0b]

I have decided to drill the new tank I'll be picking up this weekend and install a bean animal style overflow. The tank is a Marineland 120XH its called. 60X18X26 are the dims. My question is what area of the tank is best for the overflow placement, center, a corner, half way between the center and a corner, or does it even matter.
This is the box I purchased:

The dimension on the overflow is 16" x 1-1/2" x 5-3/4" for the internal box, 16" x 3-1/2" x 6-1/2" for the external box. (2) 1 1/2" bulkheads through the glass and (3) 1" bulkheads in bottom of the external box.

TIA

I am sure you will get a lot of specific responses but in reality it is totally dependent on your setup. I would probably put it on one side and your sump return to the other side. But in reality if you have substantial flow it shouldnt matter short of facing the output directly at your overflow...that wouldn't work well.

For efficiency you may want to consider how your plumbing will run given where you decide to place. Also, I tend to think that the return towards the overflow isn't necessarily a bad thing - as long as it's not hindering other flow too much. There's reason why for having the coast to coast overflows.

Performance aside, also consider which placement gives you the greatest access for maintenance if it makes a difference.

Beyond the physical aspects of the room and what will fit best for ease of maintenance or simple space, I like to consider the type flow direction to match the type fish I keep. If they are riverine and rheophillic species, putting the overflow at one end and the return on the other might match a riverine environment. If the fish are lacustrine, (lake species) or species where a none direction flow is natural, an overflow in the middle of the tank might be more appropriate.

I'm not exactly sure what species type I plan on keeping yet. So I think I'm going to lean on maintenance aspect and put it more toward one side for ease of access. I suppose I could configure the return to match either a riverine or non directional type environment.

On a side note, there is an abundance of cyano cichlids in the local waterways around me that I plan on trying to collect a single one or a pair. Below are a few of the one's I've caught before.
