The thought of "OK... that's enough of owning an aquarium" did pass through my mind.
Have had it since 1989. 30 years... over it.
But what do you do with the fish? I could not just flush them.
Dealt with a minor leak back in October, but it still involved a complete disassembly of
the whole thing. I re-siliconed all the seams and it worked fine up until yesterday. HOW
does it just fail like that? Normal normal normal.... GUSH!!! I was VERY generous with
the caulk.
Anyway... scoured the county via web to find a similar
tank (hexagonal). I thought about
one of the one-piece acrylic
tanks. A couple aquatic places sincerely talked it down. They
scratch easily. The tops severely limit access to the
tank (for cleaning, eg.) since everything
is built-in. And the material yellows after only a couple of years.
Got another glass one, but 20% less water volume. It's a step in downsizing.

Now letting
the water cycle for a while and getting all the water tests within safe readings. I'll move the
fishies to their new (smaller) home after the Sunday Dad visit.
Ugh.
