I don't think anything is really truly foolproof. Every idea has pros and cons, risks and rewards. I would hope that the likelihood of a pipe leak is less than that of a power failure/interruption. So I think a closed loop is less risk than a sump return; but I agree that it's not zero risk.

don't discount the possibility of a bus hitting the tank during a water change.

So... Here's my latest idea in thinking about this.... let me know what you guys think. How about a closed loop, with a submersible pump in a self contained container that is as high as the tank, and as low as the bottom of the sump. Pump sits in the bottom of it, and no matter what, as long as the plumbing is good the level could only get to be as high as the top of the tank level normally is. My only concern with this: How much would it cost to build such a vessel? It would need to potentially have a great deal of pressure on the bottom of it, so maybe 6" Acrylic? How much does that stuff cost? Anyways, just a thought.

doch.. I don't know what your saying!
I'm just glad I'm not on a bus route!!

Check this link out for ideas on how to stick a closed loop on your tank. You don't have to use a SCWD on there to make it work.

Oh great, thanks Willow, now I'll never get to sleep. ("Is that a bus I hear outside ?????? )

Would the purpose of this container be to hold water if the pump ever breaks a seal or the pipe from the closed loop breaks?
