opinions wanted regarding overflow for 150 gallon

[chwkreefer]

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

it only utilizes 2 90s.

it is a 1.5" bulkhead, which handles my mag12 return, which goes straight up and over the tank, using a total of 3 90s.

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...
