Unwanted snails in a freshwater aquarium?

I have had a 46 gallon tank set up for close to 1½ year now. Recently I set up a 10 gallon tank as a quarantine tank; I put in some live plants which apparently included some snails and/or snail eggs. I bought the plants to put in my large tank, and I don’t want to introduce snails into it. (Been there, done that.) Since I don’t have any fish in the small tank at this point, all I need to worry about is not killing my plants along with the snails. Should I just put chlorine bleach in there? If so, how much? Or should I, as I read on one site in my research, use a copper-based ich treatment at double or triple dose? Any jellies out there with ideas?
