Hey I'm new here, but my late stepfather purchased a custom built glass 180 gallon tank from a guy in houston that used to build them for $1000.00 bucks with canopy and stand.
All I could manage to find was the purchase address from the guy that built them.
I will say it was a well built aquarium no leaks cabinet wasn't exactly designer quality but it was sturdy.
Here is the address perhaps you could send a letter to the current resident.

I hope this helps. It was 10 years ago that we purchased it so the guy may not live there anymore.
