The walls are a bit too thick in these renderings, and the dimensions are not correct according to the first version finally decided upon -- but if I had to pick one that would look most like the box being attempted, it would be the more cube-like version.
After the box is formed, it will be tested for holding water, let to sit for approximately one month before introducing biology (fish, plants), and only after a pH test.
