You should be able to remove a steady stream of tadpoles with a minnow trap. My SMB-YP-BGxRES pond has a bumper crop of Bullfrog tadpoles this year; I'm getting a couple dozen a day with a minnow trap hanging from the dock about 2 feet down in the water.

It won't eliminate all of them, but its ergonomically correct.
