My 10 gal. Hosp. tank is empty, has no fish but is overrun with pesky snails. I want to treat the tank with something to kill all the snails without tearing the tank down and emptying everything?

Creative ideas welcome as long as they are 100% effective, easy to execute, and leave no harmful residue for future fish.

How about assassin snails? http://arizonainverts.com/blog/?p=20
They kill other snails and multiple very slow so they are easy to control, plus you get to watch them hunt and kill other snails. Some kind of evil satisfaction in that.:mad2:
