PF mentioned the primary problem with snails, Bill Cody has mentioned this in the past as well. Snails can be hosts to parasites that can effect your fish. In addition, as PF said, this can give you "swimmers itch." We use to have that problem in our pond. Once we added RES the problem was greatly diminished - in fact we haven't had any of the "swimmers itch" since we added the RES.

I don't recall anyone "stocking" snails in the past. That's not to say that it isn't done - - it's just not common.

If your pond were mine I'd add RES to get rid of the snails.

Hold on for more opinions.
