Low GH and not enough buffering (KH) can cause the shells to erode (turn
white) and the snails to die. The third tank probably has gravel with a
weak source of CaCO3 o/e in it. Some gravel has shell or marble chips that
don't dramatically change the water pH (after enough aging) but can still
provide that essential Ca to keep shells intact. The lower the pH, the
more Ca and/or Mg dissolves into the water column.
Get a combination GH/KH kit and check all three tanks every few months. I
bet the one the snails thrive in has little higher GH and KH than the
other two. Oyster-shell grit (from the feed store for chickens) or crushed
coral from the (more expensive) LFS, in a filter bag, can raise your
hardness enough for snails (and plants, etc.) to do well.
