I wrote last week about my apple nail just floating. Well, it still is
floating and now the shell which is usually a yellowish color is now getting
speckled white. I took the snail out and touched it and it moved, so it is
still alive. But 1-1/2 weeks of constant floating?

As stated in an earlier reply, apple snails do have a tendancy to
"float", but in my experience (I am not an apple snail expert), this
seems excessive.
What is your KH? Calcium is the main ingredient of KH and without a
proper KH above 80 ppm (or more), any snail will have difficulty
generating a healthy shell.

You may also have an infection, of which you are limited in what you
can treat with for this; I would suggest Pimafix, but others here may
have better suggestions.
