I repaired a 90 gal
aquarium a few years back due to the same reason. I had to empty the aquarium and strip all the old silicone out. I figured as long as I was repairing one section I might as well redo the whole tank.
After stripping the old silicone I sanded the seam areas with a fine grit sandpaper 400 or 600 grit, I can't recall. You need to do this to remove the minute particles of silicone embedded in the glass that a razor blade cannot remove as silicone does not bond well to silicone. After this, wipe the seams with acetone and let dry then apply silicone making sure no bubbles are in the applied silicone when done. Let dry for at least 24-36 hours then you are good to go.
