Pulling a sump out

[bullit67]

OK I have a conundrum I once my sump room is finnished and my new sump is set up I have too deal with the old 75 gallon sump under my stand. The problem is to get it in there I had to remove one of the supports off of the back of the stand ( I put it back once the sump was in place) So now the only way to remove it is to take it apart. I would leave it there but I want the room. I was woundering if it would be worth my time and effort to rebuild it once I get it out I have no use for it but some one else might be able too use it. Has anyone here ever attempted to reassemble a tank if so how did it turn out? how did you do it? what silicon did you use?

any help would be great
