First Tank Build! Does this piping make sense before I glue?

[ELynn]

Hello Everyone! This is my first post and my first tank! I have wanted a reef tank since I was young and I’ve put a lot of effort in to researching what would work for me. This is the dry fitting of the sump on my 75gallon, anything look concerning before I glue it down. The tank on the side is an external refugium. My only concern is maybe the soft tubing for the drain, anyone ever have issues? Thanks!

This is the main display.

Looks good. Ideally enough PVC plumbing from the overflow connected to a gate valve is preferable so you can adjust the flow and eliminate any noise. But a section of soft tubing at the bottom should be fine.
