Setting up a new 350. Ran sumps in the past but it's been a long time since I've gotten back into it. My drilled holes are 2.5 inches so you figure 1.5 inch bulkhead and 1.5 pipping. I know there's a breakdown somewhere but what GPH pump would I need too get so the flow in the sump is correct and do yall recommend Any brands?
How much GPH do i need?

There is no "Correct" really. And depends on your exact setup, what is in the sump,how the sump is set up. If it's a full siphon setup 1.5" piping can handle somewhere in the region of 2000gph. If it's not, more in the 1300gph range. So, I'd probably aim for a pump that will produce about 1000gph
