Overflow...cleanest, reliable option for rimless tank w/ clear back wall

[duganderson]

What is the cleanest looking overflow option for a 30-50 gallon rimless tank with glass back wall that is reliable (not fail and flood your house)?

I'm also open to other non-traditional options like the Mame overflow, etc.

Photos, links, etc. appreciated

External overflow box, on the side, with a bean animal fail safe.

Sounds tricky! You want an overflow on a clear back wall? Maybe run the pipes down behind the corners of the tank, so you don't see them as well. Or you could do an internal, black corner overflow that goes bottom to surface, so the pipes are hidden within.
