Thanks. I have the sump o the ground with my current 75G setup. I was looking to raise the sump but wasn't sure if it mattered how much the plumbing dropped before the vertical run going thru the wall. So it won't matter if I drop say 4" out of the external overflow, then a 90 and a 12"vertical run thru the wall and another 90 with a short piece of pipe so it's submerged under the water in the sump ?
