If power goes out the tank won't overflow with or without a sump. Drilled tanks such as you're considering have little to worry about with overflowing since the overflow isn't dependent on a siphon and rarely ever get clogged.
has a ton of info on sump setup.
I think it's a great idea since added water volume is good with either FW
with the added bonus of being able to hide equipment and provide the tank with good circulation.
With a 180 tank I'd look at a using a 55 gal
tank for your sump which you can build yourself. This post goes into the details
. You will still need baffles to control bubbles.
I'd have them drill two overflows with a 1.5 inch Bulkhead which will give you close to 800 GPH
for each overflow or 1600 GPH
total. Don't forget to ask for two return 1" bulkhead holes.
has a great pump overview for selecting the proper pump. Main thing to remember is to get a pump that doesn't exceed your overflow rating at the proper head pressure.
I'd put the overflows/returns in the corner personally.
