one or two overflows?

[eric b 125]

i'm drilling my tank soon, and yesterday it occured to me that my plumbing would be easier w/ less head-loss if i go w/ dual corner overflow's and a center return that splits into two returns rather than center overflow and corner returns. everything as far as plumbing is exponentially easier this way. what are your opinions on this? my sump will have skimmer chamber and fuge w/ center return pump.

i think two overflows is the way to go if i was you.

Depends on the size of the tank and the size of the overflows. Small tank 1 overflow. Example I have a 125g tank with two 1 1/2 drain lines going to 1 overflow box in the center of the back of the tank. More than enough for me.
