I remember as a kid reading an article on carbon in one of the aquarium
magazines. The author referenced several experts with opinions on the
lifespan of carbon that ranged from very short (hours or days) to indefinite
(it never wears out).

For what it is worth, I use carbon in an in line filter to remove chlorine
and chloramine for my tapwater supplied automatic water changing system. It
lasts about 6 months under my conditions. I do not use it in an aquarium filter.
