Splicing in a different pump for Tunze ATO?

[asylumdown]

Oh wow, that's totally brilliant. That just solved easily the biggest conundrum I have about my tank set-up. Though, I'm confused by this line in the product description:

"Does not work with pumps having a grounded plug in."

The grammar is wrong enough to not be clear (though likely saying plugs with a ground prong won't work), but the photo shows what appears to be a grounded socket....
