What are your thoughts on me doing it this way with 2 - 1.5" drains? What pvc parts do I need on either side of the bulkhead? or can I get a non threaded bulkhead to just slip the pipe in.
Could I even go down to 2 - 1" bulkheads? How is this setup going to be for noise.
Thanks for your details btw. I appreciate it. Now I am starting to think about doing the overflow as per your drawing just to keep the tank area bigger.
I would at some point change to flexible pvc or vinyl to minimize the amount of elbows going to the sump.
Thanks,
Bill

just so you have an idea of what kind of flow i am seeing through the overflow.
so you could certainly use this design on the non-viewable end of your tank. and make a small overflow box, as i did. you could even incorporate a second bulkhead to it.
kinda like this...
