6 foot tank / overflow design [feedback or ]

[loops123]

Hi all,

I'm close to sending the below to my tank builder but would appreciate your input before I do.

It's pretty much a standard 6foot with an internal bean animal overflow.
6ft x 24" x 24" (170G)

I will be aiming for 3-5x filter turnover.

Does the 3 x 1.25" and 2 x 3/4" sound right for the overflow?
Any recommended changes or other consideration would be very much appreciated!

Thanks!
