Come on kida, still watching here also, cant wait to see it filled as i think i said before your build is very close to what i will be doing but 7x4x3, i will have to take the window out of the conservatory to get it in and thats the biggesr window and hole i can make...so SWMBO says LOL.
I am going to look at getting the corner window bent out of one sheet of glass, but if yours works aswell as cvermeulen tank has it will be more cost effective.
You can see the web cam I put in the tank as well. Made a little housing with leftover acrylic and 1" pvc. Plugged it into a usb/ethernet adapter. Ran it to my pc and now I can watch fish from my office.
