How hard is it to re-seal a tank? Is there anyone out there with some experience I can pay to do it for me? I am not sure I want to risk doing this myself and coming home to 100g of saltwater and coral in my living room. For those of you who know of my luck, if it will happen to anyone...it will happen to ME!

Also, I heard at one time if a glass center brace in a tank breaks or is removed, replacing the brace is basicly useless. Is there any truth to this? Do I just silicone a piece of glass back in replacing the broken brace?
