Smallest overflow?

[juke]

Has any one out there come across an HOB overflow no wider than 5"? I am looking for options to add a sump to my 24DX Nano cube

Any thoughts?

Drill it and use a standpipe.

You can make an overflow very inexpensively out of PVC or black ABS.

Most siphon overflows are mostly identical in functionality. I just built mine this way since the tank it was used on remains only 2/3 full. It works great, you would just have to downsize it.
