Plumbing Help

[alf1096]

I currently have a 65 gal tank and run a eshopps overflow. I have found a used 125 and it has 2 overflow with 2 holes per overflow. My question is what is the best way to plumb the tank. I was gonna do a Herbie but would like to use one or two of the holes for a return so I don't have to go over the back of the tank. I guess I can go over the back of the tank if that's the only way. My only requirement is that it is silent.

Don't want to buy the tank if it will lot do what I want it too.

Why not look into a Bean Animal overflow system
The tank has 2 1 inch holes and 2 3/4 inch holes I believe
Use first 3/4 inch hole as a full siphon drain
Use second 3/4 inch hole as your return from the sump
Use first 1 Inch hole as an open channel drain
Use second 1 inch hole as the Emergency drain.
No holes in the back or pipes on the back.
Use the holes you already have and it is very easy to set up.
