I have a 40B as the display and a 20L as a sump . I was wondering if I had a 1.5 bulkhead with a 1.5 Durso Standpipe which Home - Durso Standpipes says should give you about 1,500 GPH, is that to much draining a hour? And what type of Return Pump would I need to pump up 4 ft. I've read so much different places I'm just so confused.
Help with Return Pump and Overflow.

Nope, it's more of what the sized drain can handle, the return pump dictates the amount but, you have to take into consideration things like max head loss and so on to calculate the actual return values.

You first need to determine if the bottom glass is tempered. Tempered glass can NOT be drilled. Why not put a Glass-Holes overflow on the back wall. Takes up a fraction of the space of a conventional overflow, and even comes with the drill bit to drill the hole. I'd consider the 700 gph Glass-Holes overflow for a 40 gallon tank.
And as far as a return pump, I'd be looking at a DC pump......like the Jebao DCT-3000

Thanks for the help. As for the Glass Holes overflow that is what I want to do but this is a used tank that has a hole drilled in the back-left-bottom-corner. I don't know if somehow you could seal the hole using silicone?
Thanks anyways.

To block off that hole, leave the bulkhead in it and simply install a plug......whether it is threaded or slip. Hope that makes sense.

According to what you want of course, but I'd be hard pressed not to use the drain that comes with the tank. (Get a new tank if you want a new tank, after all! [emoji106])
As was said already, drain size isn't much or a factor - it dictates noise levels as much as anything else. At 1.5", your drain should be about as quiet as possible.
As for flow, you only need 2-4x your display's volume, or between 80gph and 160gph. 200gph would be more than plenty.
Those are actual flow numbers for your tank, BTW, not the flow rating on the pump. Depending on the plumbing you need to get the water from the pump to the tank, a pump rated 300-500gph will probably do the trick.
