Would this work?

My 410 split two seams this morning. It is kind of strange because it was sitting with water in it for a few days and it had only a small leak, then after about 12 hours with the pump and skimmer running, the seam where the overflow connects to the glass split from the top to about 2/3 from the bottom.

Anyway, I can't seem to find an aquarium repairer in the Atlanta area that will even attempt to take the glass apart and reseal it. Thus, I'm left to do it on my own.

My idea is to reseal the seams. One seam is split in the corner where two pieces of glass meet at the back on the tank. The other seam that is split it where the overflow connects to the glass. I was hoping to reseal these areas, then put vices on them permanently. Afterwards, use molding and dry wall to make it so that the vices cannot be seen when looking at the aquarium from the front. My only concern then is the seam where the overflow connects to the glass. Would this work?

Any ideas and help are appreciated.

The thing that comes to mind (not sure why it didn't on your other posts) is why did the seam come apart and will all the others follow suit soon? 410 gallons is a lot of water to end up on your floor not to mention the dollar value of the livestock that you could theorhetically store in that size tank (10's of thousands of dollars I am thinking).

I don't know for sure but I think the only way you can be sure of a quaility seam (and seal) would be to cut the existing seams to get the side panel of and then scrap the silicone off the glass so you can start over with a fresh surface.

Glass aquarium repair (http://saltaquarium.about.com/library/weekly/aa050200.htm)

cut & paste....

Locate the section that needs repair and mark it, using some type of material that will not easily wipe off with water, i.e. a piece of masking tape, a felt tip marker that can be removed later with windex, etc.
Remove all inhabitants, drain the tank, and remove the substrate.
Rinse out and clean the tank with freshwater, then turn it upside down and allow the water to drain out and dry. You can wipe it out with a clean cotton cloth to speed drying if you desire.
Relocate the section to be repaired and again mark the pane to be removed so you know which side of the glass is inside, outside, right, left, up and down, etc. This way when you reinstall it, it will be going back in the exact same way it came out!
Take a razor blade and run it between the panes of glass to sever the silicone, and completely remove the pane. Be very careful and don't rush this step, and do not try to pry the glass pieces apart. Allow the razor blade to do the job, just working at it until the pieces separate pretty much on their own. Glass breaks very easily when pressure is put on it, and the edges can chip, making your repair job a much larger task if the glass gets damaged.
After the pieces are separated, thoroughly scrape all the old silicone off with the razor blade, dry the joint areas, clean the surfaces with acetone, and allow all areas to dry for a few minutes.
Cut 4 strips of duct tape, about 5 inches long, and stick them to anything close by within easy reach that has a clean surface to it, that the tape won't stick to too much, with at least half of the tape hanging down freely.
Apply a thin but adequate solid line of silicone to the inside edge of the glass areas to be joined together, then, at a slight angle, place the piece onto the bottom base glass pane (in the exact way it was taken out), slowly tilting it upright and pressing it lightly, but firmly, down into the silicone.
Secure the piece of glass from moving by taping it into place with two pieces of duct tape, each placed about 1/4 of the way from the top and the bottom, wrapping them around each corner from one side to the other. If you have trouble with the tape not sticking to the glass, just clean the area with some acetone on a paper towel and try again.
Apply another solid line of silicone sealant along each of the inside glass joints, and run your thumb over the silicone from one end to the other of each seam to the smooth the silicone down and force it into the joint areas.
Allow the silicone to cure for 24 hours.
Refill the tank with freshwater and allow to sit about 12-24 hours. This gives you a good test period, and you will feel much more confident of success when you finally fill the tank with saltwater, put it all back together and add your inhabitants.

Yep, it looks like I'd be taking it apart.
