I have a whole lot of snails- now what?

My frog tank I was using while they were being raised as tadpoles had 1 snail in it. Weeks later and there are 100(exaggeration?) Microscopic snail babies on the walls and some medium sized ones on the rocks. My frogs are in a different tank and in frog mode, but what on earth do I do with all these snails? I don't want them to be invasive, I don't know if its too risky for overpopulation to try and feed them to the frogs. What on earth do I do?
