Plumbing double check please!

[FrostyFins]

Hi everyone,

I think I'm just about set on my plumbing for my new 60 breeder and 20 long sump but would appreciate a critique before I glue things down since this my first time plumbing one. I need to add one more slip/thread coupling to connect the return Tee to the pump.

I plan on adding a spreadsheet with costs, parts and item numbers later for a full accounting of this build, and any advice is appreciated.

Thank you!

are those spring checks on your return?
If so i would remove those and use a simple siphon break hole at the water line. No need for checks.
