seriously though awesome tank! haven't seen
one of these oddball tanks in a long time. pretty
much what everyone said is the best way to fix
this tank. remove old silicone completely and
redo everything. if not the tank will fail along the
way.
get some razor blades, silicone, caulking gun,
guitar string, clamps and some bar keepers friends.
then your ready for a new repair project.
