Try "Had-A-Snail", a snail killer. I found it at Petco. It's just copper 
sulphate at 1.63 % dilution. But beware, it may stunt or even kill sensitive 
plants such as valisneria if used at the recommended dose (for killing 
snails), which is about 0.1 ppm. It made a difference in the hair algae in 
my tank, but didn't kill it entirely. IMO, nutrient control is safer and 
more efficient, although slower.
