I have limpets in a nano tank and would like to rid myself of them. There is no fauna in this tank at all. Only HC, dwarf hairgrass, aquasoil and wood.

Is copper a good method? If so, how much? Could I simply drop a penny in the filter and remove it once they are dead? Will that increase the copper levels high enough to damage my plants?
