(sorry to make it sound confusing) You might be ok. Test it in a bucket to see if it restarts. When it stops draining, add more water to the bucket to see if it drains more water without your help.

edit: I was agreeing with rally but was not aware of issues with larger piping...don't see why though
ethnics;485197; said:you dont NEED two, just more flow if u have a stronger return pump. each of your overflows should be around 5-600gph so havin two would mean it could support atleast a 1000gph pump wih proper headheight
I'm quoting this big because I didnt listen to this. I put 1, 1" overflow on my 125g. My mag 9.5 was starved for water and would not function right. I had to build another overflow and attatch with a "T" My tank now cycles perfectly (at least from my newb opinionethnics;485197; said:you dont NEED two, just more flow if u have a stronger return pump. each of your overflows should be around 5-600gph so havin two would mean it could support atleast a 1000gph pump wih proper headheight
