I have no idea what size I need!
I have a 72G bow front that needs drilling & a 20-ish gallon sump.
I'm guessing a 1" or 1 1/4" will do.
I hope to build a herbie, so 2 holes out & one return? Base glass is tempered so I'll have to drill the back or sides.
Funnily enough I do live right by the airport!
You can always land in the nursery playground behind my house, will give the kids something to talk about for weeks
Actually scrap that, I might get sued by some angry parents!
