Quick question everyone, i mounted this on my tank and its leaking like 1 drop every 2 to 3 minute. This is the order of the install Bulkhead/Box/Gasket/Glass/Gasket/Nut. Should i be adding another gasket inside the box where the bulkhead is in contact with the box? Or is there a different order to do this ? Thanks in advance.
Bulkhead mounted overflow.

A picture of what you are doing would help understand.
If it is what I think the flange side of the bulkhead go on the outside with the gasket.
Sometimes it is recommended to use two gaskets.

Follow the box manufacturers instructions, get the instructions if you don't have them.
Trace the leak to the pipe joint where it is leaking. Take it apart and inspect everything, especially the sealing surfaces. I've seen a plastic raised nib defect on a bulkhead sealing surface, it wouldn't have sealed if I didn't notice it and remove it.
Sometimes I use a little sealing lubricant on gaskets and o-rings. It's called Lube Tube w/ PTFE. It makes it easier to form a good seal, sold at pool supply stores.
