Can you fix a small crack in a 6 gallon acrylic aquarium Eclipse?

Is on the side of Bowfront aquarium about 1 1 / 2 "of length from the top. Is there a way to this label? If I just put a piece of tape on the outside to stop the spread of crack?

There is a specific glue that is used in acrylic, which is called solder 16. It's kind of Solvant and melts the acrylic together. You can get Here: http://www.rplastics.com/weldon16.html I tried using it in a cheap-or 6-gallon tank I picked up at a yard sale and was broken on one side of the top to the bottom. And although I have a mess of it and it looks terrible, that holds water, no leaks and makes a fabulous quarantine / hospital small tank. The welding of the seal will the crack and prevent it from spreading.
