Mhm, some people like the snails. They eat excess waste, and won't get out of control unless there's too much stuff for them to eat lying around. If the aforementioned method doesn't work, there are a lot of fish species that simply eat them. It just depends on if you really want them gone or not.
At my LFS, they have driftwood with tons of snails on them, but I have two small catfish so even if I brought it home, I know I wouldn't have to struggle with it long. Probably serves for a tasty snack for them, too.
The cucumber will probably work though, if there's not much other food sources in the tank for them to eat, since you're cycling.
