? are you placing the baffles in a glass tank/sump or are you building the entire sump out of 1/4" cell cast acrylic?

Bieng that you are going to have a 20G display, I would drill the top corner of the 20G for a 1" bulkhead and have the drain be gravity fed from top corner so you get apprx 200-240gph drain. this way you can do away with the overflow box and have more interior tank room.

I have a 40G with a interior DIY overflow box using 1/8" cell cast acrylic and I have two 1" drilled bulkheads with screens inside the box both draining to a 30G DIY sump/refuge. The return is a 550gph powerhead feeding a 1/2" pvc spraybar.

I have two 29G that I drilled for 1" bulkhead and are gravity drained @ the top corner of display tank going into a 10G leader glass tank. these two 29G have an interior 1" elbow pvc for skimmer/drain.

All my sumps have a durso setup to stop gurgling noise as well.
