I think it was craned into place after the walls were cast. Don't know if they brought it in from the top or through the opening leading to the pond. Those pics were'nt in the aquajournal. It's a work of art. More stainless than a Delorean. Full of Altum angels.
Heres some recent shots from Ben and Ricky of the DFWAPC. They went a few weeks back for the ADA party. Lots of nice shops, and some really nice pics of Amanos home (Big tank) and the ADA gallery.
what makes you think the tank wasnt made in its location as that how most big tanks are made (it could also be made out of acylic ) then 4 men could have lifted it anyway
get all the flowers out and put a few rays and a shoal of arowana and the tank would look sweet
You can see the filtration in some of the pics Ricky and Ben took at the link above, there is also a large sump behind the tank under the tile that you can't see.
