Be careful. Turbo snails are, how can I say this in a very subtle way, oblivious, I guess?...well, they're d u m b. Sorry for thye french.
they are, however, great in keeping rocks and sand clean. They actually grazed on my sand. The problem is (a) they knock things over, and (b) they get to your powerheads and sometimes, if they're not lucky, get sucked in.
Good luck
