Any molluscide you use is likely to kill fish as well, but even if you found one that killed the snails and the fish didn't die, the water will become toxic because of the presence of so many dead bodies. The usual means of preventing such an infestation is to quarantine plants before placing in your pond, to check for any kind of pest such as this, or '...

Garden snails eat plants, fungi and algae, depending on the type of snail, so no, I'm afraid they won't be eating any pests... you could provide food for them in the form of lettuce or dandelion leaves, if you really want to encourage them.

If you have a small amount of lettuce plants then just going outside at night with a flashlight and hand pulling off plants and the ground will be sufficient.

You can either inspect regularly and remove any you see, or use something that ...

A saucer of beer will attract the snails if they are the type to come out on land at night, and they'll drown in the beer. Snail eating fish is a good way to keep them in check, goldfish eat just about anything.
