I think you would be fine with the two 300G max ans ONE pump - have a look at 2quils three for his 125 Build he has a neet drawing there. I always look at it this way if you have two pumps then it is just another plug you have to use. Most of the typical set-ups have too many plug ins to begin with. But seriously two overflows one on each end would do a nice job and your return in the middle.
Sorry - the bigger the better for your sump/fuge - I think anyways see what the others have to say.

Yes - Looks at 2Quils build - he has the exact same tank.https://forums.saltwaterfish.com/forum/thread/378912/2quills-120g-re-build-thread

i have a 125, as well. two pumps would make matching the overflows and returns too difficult. if you want two returns, just split the return line from one pump. i used a SCWD to split the line and split each side again using loc line.

i dont personally have any experience with siphon overflow boxes, but if you get two of the same boxes (ones that dont lose siphon) i dont see a problem. i maintain a tank that uses the cpr overflow box with aqualifter pump and the pump failed a few times.

Some great builds!
I was going to use a syphon overflow and not drill it though..
does this change anything?
If you have a chance now to drill your tank I would say drill it, you won't be sorry later, it really is not hard to do.

Agreed, for what you are going to spend on a external overflow you can go to glassholes. com and purchase a kits that has everything you need to drill your tank except for the drill.
No need for two pumps. Split your return if you're looking for 2 outputs. But running two pumps can be done as long as they are in one sump and not seperated from eachother by running two tanks for your filtration.

try glass-holes.com. i think there's a hyphen in there. that's where i got the kit you see in my build thread. honestly, drilling the tank was super easy. i nearly chewed my lip off while doing it, but once the first one was done the second one was easy. i would urge you to really consider drilling the tank. i know you already have the overflow boxes, but that doesnt mean you have to use them

What brand are the overflows and the pump? You say you have a 300gph hour pump...is that before or after you factor in head loss? Honestly I would advise against seperate overflows as well as seperate pumps. Running two overflows is just that much more potential for a problem occuring incase of a loss of syphon. If you could take them back and get a single, larger overflow would be better. But the problem that I see here is that 300gph for a 125g system with sump is very low for this size of a set up. I'll be pushing the low end on my 120g with sump at 600gph. Some folks go higher.
Also, running your overflows at half of their capacity typically means that you're at more of a risk of losing syphon. Manufactureres that I spoke with over at CPR tell me that the syphon is most secure when you're pushing your overflows close to their maximum capacity as you can without going over.

The pump I have now is 720GHP, 300 with head. I think I might try the drilling.. What is a good 700GPH pump with 4 ft head?
Eheims are probably most respected for their reliability, power, quietness and least amount of heat transfere to the tank. The eheim 1262 or eheim compact 5000 would be a good choice for your size tank. One of the more popular brand of pumps but probably not as reliable are the Mag Drive pumps. I think a Mag 9 or 9.5 would be the appropriate size for your tank.
The thing about the drilling is never having to rely on maintaining a syphon to keep the drains going. It's all done by gravity so there is alot less to worry about there as far as flood occuring.

If you drill you tank like that site. I would think having more flow you need would be advised. But, that is just if you go that route.
Im not quite sure what your trying to say here?

Ok so if i went with the 700 max overflow drill kit, would i place it in the center of the tank or the side? Do i need to drill the return? Or would gravity work against me here?

i went back and forth for a while about drilling the returns. i opted not to because it was easier to control the siphon break level on non-drilled applications.
