What is a good size bulkhead for a built in overflow, if you are running a Mag12? I was thinking 1.5" but does it have to be bigger?

1.5 " hole or a 1.5 " bulkhead to fit 1.5" PVC
there is a differenace.

1.5 " hole will fit a 3/4" bulkhead
and a 1.5 " bulkhead you need a 2-3/8" hole
but for plumbing a 1.5 PVC that is plenty for it .

There is an overflow calculator on ReefCentral in the calculator section, it should help you decide which is best suited for your tank. It should be on their home page. :biggrin:

1.5 bulkhead will handle a mag 12 easy.
