I was initially a bit nervous of the idea of cutting a slot (never drilled glass before, let alone cut a slot), but as you say, all the pressure is at the bottom of the tank, and the overflow will brace it anyway. I'm thinking I'll make the slot pretty long (almost coast to coast) and narrow so I don't need a grating across it. Will look really clean I reckon.

I just needed a nudge in the right direction..
