Mentioning a dead snail, I added 20 sand snails but haven't seen a single one come out....could they be causing this if they are dead??

It happened to me before, it took me a couple days before I found a couple of dead snails causing that kind of smell. If it smells like something rotten, I doubt very much they are the culprit.
