I am currently in the process of trying to reseal a tank. This is my first time doing this and I have read a lot of post on here about it and I have watched a few videos on youtube. I have been removing the old silicone from the tank and the sides were pretty easy, but on the bottom of the tank I removed some silicone, but it appears that the bottom pane of glass is made shorter than the footprint of the tank and is surrounded by silicone. I don't know if that is a good enough explanation, but I will add some pictures later. From what I have learned researching is that I can strip just the silicone that is holding in the water and not the silicone that is actually holding the tank together. The silicone that is around the bottom pane appears that if I remove it that the pane will possibly come out. From the pictures and videos I have seen it doesn't seem like this set up is common, do I have an unusual aquarium? Should I take that silicone out? Any advice will be greatly appreciated.
 
You only need to remove the silicone that is in the interior of the tank. Leave the silicone alone that assembled the glass panels to each other.

The bottom pane is surrounded by silicone. It isn't like the rest on the tank, it appears that the silicone in the bottom holds it together as well as keeps the water in.

This is a picture of the bottom of the tank. As you can see the bottom pane of glass is separated by some space and silicone from the side pane. That is the biggest gap which is the front side of glass, but there is a gap all around. What can't be seen in the picture is that that space of silicone is level with the glass, if not a little lower than the glass. It is like a grove or ditch is there and the silicone is down in there. I believe this tank is an older tank, and it is a large tall tank. The glass seems to be very thick.
 
Well all I can say is to clean the glass on each side of the seam. Then cover the whole thing from with enought silicon to overlap the seam and glass on each side... wait 36hrs then do a fill test.
