Some progress. The stand is built, getting caulked and waterproofed. Simple overbuilt 2 x 6 construction. A pad comes with the glass tank, which will go between the plywood and the aluminum frame.
The tank comes in 48 hours. I'll probably do a fill test. Better the tank explodes now then later...
Oh, yea... and the house has a floor, walls and some windows.
The hidden "library" is to the left, living room to the right, access closet in the back.
Can I come for a swim when it’s done? In a friendly “swim with the fish” kinda way
