Quick question about fill level on new tank

[Peepers]

Hey guys, so I'm filling my new reefer 350. Had a question about when to stop filling. Im running rodi line into display tank now. I had figured I'd run it until it hits the overflow, then continue filling until sump level is full in return chamber??? Then turn on return pump?

Sounds like a good plan to me. Overfill the return chamber just a bit to compensate for the water not yet in the plumbing.

Thanks. I've never done it before, but seemed like the logical way. Just wanted to make sure. Lol

Bring the water level up a couple inches over the baffles. That should be pretty close.
