Dual Overflow Question

[ph2505]

Planning out a build, had a question about the plumbing of a dual overflow. i am planning to have 2 island overflows with 2 holes in each, total 4 holes. I am planning on having 2 return lines, my question is, are you able to split up a Herbie style overflow or do the two pipes need to be right next to one another?

Overflow 1:
- 1st return pump line
- Herbie full syphon drain line

Overflow 2:
- 2nd return line
- Emergency drain pipe

would make sense you could split it up but just want to see if anyone has any experience with this? thanks

I was wondering how this would be set up for an Aqueon 120, replacing the dursos. The problem is that water is going to spill over both overflows and the emergency one will fill until it overflows to the sump. (hope I said this right) I could be wrong though. Needs more thought. lol
