Bought a somewhat grungy Craig's List 29 gal bowfront tank, and after cleaning it found that the thin edge of the silicon adhesive bead pulled away along about 8 inches of the front bottom joint (see pics). There are no leaks and the adhesive bead appears otherwise still tight except for this small area of loose "fringe" edge. The joints between the glass panel edges look sound. The tank is 8-10 yrs old, so I'd like to reseal it by removing the inside bead, then applying a new corner bead of adhesive on all inside seams if that would be adequate. Disassembling and reassembling the panels on this tank with 100% fresh adhesive is more of a project than I want to take on.
