I've heard different things about putting a valve on the return pump.
On mine, I have a 'return loop', where I can open a ball valve and redirect the flow of the return back into the sump. This lets me dial down the flow to the tank without restricting the pump. I heard it was bad to restrict the pump and it can burn out quicker.
I have also since heard that it isn't so bad to restrict the return pump, and if it IS restricted and less water is moving, your pump actually consumes less wattage.
If you are worried about it though, you could cut the tubing that goes back to the display, put in a hose barbed Tee connector, put on another piece of flexable tubing on the Tee that returns to the sump, then put your valve on the end of that piece of flexable tubing (or inline or whatever.) That would allow you to dial down the flow to the tank while still allowing your return pump to run unrestricted. If you closed the valve, 100% would go to the DT, if it was full open, the water would go 100% to the sump (or almost all of it, way easier route to follow since it doesn't have to fight gravity.)
