I asked these questions some time back, but I' keep losing the
fido feeds I select and never received any answers if they
were posted.
My very large apple snail's shell eroded (from the tip at
first).  He seemed active and healthy, but his body seemed to
get bigger and no longer fit properly in his shell and it
became very pitted and thin.  He finally lost his "cap", that
disk at the end of his body that closed his shell.  He only
lived a couple of days at that point.  This happened over a 2
year period.  I added sea salt at each water exchange...  is
there a needed mineral for these?
My pH slowly dips and I need to use pH-Up from time to time.
The decorative shells in the tank dissolve away, too.  I left
them in there, thinking that they might provide something
useful for the snails while dissolving mineral into the water.
 I don't run any natural plants as my Dempsey rearranges the
 tank each evening.  All my fish remain healthy and my snail
 is my first loss in at least a year.
