Leeches arrive in blackworm batches. There were some in mine, and I picked them out of the batch with tweezers before adding the blackworms to the tank.
The good news is they're easy to pick out with tweezers. There aren't usually many that show up in a blackworm batch, so you probably don't have very many. I'd just pick them out when I found one. I don't think there's any way to treat for them without killing the blackworms. I wouldn't worry about it and just keep an eye out for them and pick them out when you see one.
Also, depending on what kind of fish you are going to add, the fish may eat them. My corys seem to eat anything attached to the glass like that. They won't eat the pest snails, unless I smash them first, picky devils, but they appear to have taken care of little planaria type worms that would crawl on the glass. The corys go up and down the glass, eating algae and whatever is on it - other than snails.
