I'm not sure if right or wrong are the words. Does it work well for you?
Here's mine. Sorry it's a mess:

BRT (black on inside) on left. The little tupperware in the middle is a water bath for egg incubation with larval tank water. Right side is just an old water bath right now. The space is there for a second
BRT.
The second shelf is available for a couple of
10 gal. tanks. My original thought was to float goldfish bowl kreisels in there.
Under the tanks:

And a closeup of the
BRT return and overflow:

The return comes in and straight down the middle to within an inch or less from the bottom of the tank. The incoming water hits the bottom and shoots out to all sides to create a circular flow all the way around the tank. The overflow is high on the side and is pipe covered with mesh screens. All of that section is moveable and I have different screen sizes for different purposes.
