ADA tanks are all hand made and checked to perfection. Are u sure that's not a replica? I have an old 120H with stand and they are perfect. Plus I have a 60H tank with stand and they are perfect too.
How close in dimensions are the stand and tank? Are they flush on all sides?
I got 5mm to spare since my cabinet has some leg room for this type of thing.
It´s not a replica. Bought from a German ADA distributor.
About 1,5-2mm half way across the pane. Same on the other side.
