Finished and installed the internal overflow box.
The box was made with two pieces of acrylic and I planned for it to run the entire length of the tank. The pieces of acrylic were welded together using weldon 16. And the final internal box secured in place with aquarium silicone.
The internal overflow box was made to be as low profile as possible. Which meant that the elbows inserting into the bulk heads are not removable from the box. May regret that decision later.
