Ok, let's say that happens. Let's even go so far as the parents admit it and drop off a brand new tank in the driveway. Then what?? I just reviewed the build thread
No easy task to replace that tank, house critters and reassemble. It would be months before it looked "normal" again, the work would be several full days, and that's just gonna suck. No happy ending to this, unless you can polish most out in the time you can actually keep a fully stocked tank drained.
