bulkhead question


New member
can i drill my tank and put in a bulkhead for returning water to my sump, or do i have to use an overflow, so many people tell me i have to use an overflow, but i was seeing how an overflow works and if i put the bulkhead where i want the water level to be , wouldn't it be the same thing essentially .

any help is appreciated thanks guys

You can and many LFS use this method for their selling tanks. The drawback is it limits the linear surface that is being skimmed so overflow boxes are recommended.
