What Configuration For 40gal Breeder Overflow and Return?

[Enigma]

Well . . . Hubby would like to use the overflow setup that I linked too.

I do have an idea for a safety net that should work quite well for the setup . . . basically, my little sump will go inside a much larger container (another aquarium or a rubbermade, or something). As long as the returns are positioned properly it should be a sufficient solution: at least it would give the back-siphoned water a place to go.

I do really like the non-drilled returns in that photo. I think we'll try that and see how it works. If I don't like the way it works we can drill the returns instead.
