Well I finally got to do something to the tanks today. I got the top shelf of the stand situation figured out. I ending up undoing the top some and shimming it. Now the aquarium touches the shelf and is flush with it. So I hopefully don't have to worry about leaks, cracks, ect. with the tank. I cleaned up all the glass on the tanks and added a black background to all the tanks. Tomorrow I plan on doing a leak test.
Here is a not so good pic of the tanks.
