Help with return plumbing

Here is a picture of my sump

The pipe I’m holding I just need to know how far I should bring it down from the bulkhead.
Sorry for making it complicated.

It doesn't matter at all. I would strongly recommend you try it the way you think makes sense, dry fit, and then evaluate. You can do it any way you want and it will work just fine. The less elbows, the less flow restriction, but I personally don't care about that because I oversize my return to have excess capacity for future uses.

haha, are we getting terminology mixed up? Return is where you bring water from your sump back to your main display. Drain is where the water comes from your main display to your sump. Just wondering if that's where we are all getting tripped up?

Yes this only for the return

How far you bring it down is really going to be determined by where you want the lateral run located. I'd start that and then work out connection to the bulkhead and connection to pump. Tweak as needed.
