Good Sand Sifters/Algae Ridders?

[foolontheplanet]

Hey all, i'm about to head to the lfs to pick up some snails to take care of my algae problems, and i was wondering if anyone could tell me a good kind to get that not only mow through algae quickly, but also do a good job with taking care of the algae on my sand/stir up the sand a bit? So, pretty much, what are your favorite kind of snails to take care of algae in a sandy substrate. Any help is great

 

oh, btw, i hate it when people do this, but i'm gonna re-post this in the begginer forum too, since that one seems to get more reply's.
