No reason to rush this thing. It's never worth water on the floor and dead livestock. I removed the front and side panes to re-silicone the structural joint. I didn't intend to rebuild the whole tank. These types of projects have an untold number of hurdles.
Once it was re-assembled I started on the bracing. The first pieces to go back on are the original end braces.
The second set of pieces are the front and rear euro braces. I had the inside edges flat polished for a smooth non sharp edge, they are 4" wide out of 1/2" glass. A simple jig was assembled from 2x4s and ratcheting tie downs. This process was a bit nerving as the glass can get stuck between the end panels quite easily.
Inside doing some final cleanup before I put the seal on. It's a lot easier when you can get in the tank
