So I am very familiar with the concept of a sump and an overflow, which is why I totally understand holes/bulkheads near the top part of the aquarium. However, I have been doing a lot of research lately and watching a lot of videos and I am interested in possibly drilling one of my own tanks in order to install a bulkhead and a sump/refugium in order to avoid having a HOB overflow box.
What I don't understand is what is the purpose of a bulkhead on the bottom of the tank? I mean, there's substrate there, right? (at least on mine and most every reefer's tanks I've seen) The only thing I can possibly think of is a pipe coming straight up through the bulkhead all the way to the surface and maybe use the pipe as a skimmer? (but the suction sound would be ungodly loud)
Please help me understand what I am missing because obviously I have totally missed something and I really want to understand?
Thanks.
