Seamless "pond with window" or has anyone sunken a fish tank inside their pond?

  • We are currently upgrading MFK. thanks! -neo
The requirements for the strength would be the same as for a conventional viewing window for a 8'-9' deep tank but I can understand the apprehension.
 
It's envisioned to be open at the top, as this is how you'd get in and out.
