How much smaller do you want it? I just replaced normal gravel with EC in one of my 10 gals and it's perfect for my carpet plants (normal and dwarf baby tears as well as clover). The biggest grains are smaller than the normal gravel pieces of my previous set up. Instead of using a hammer, why don't you get a pill crusher. They have them at drug stores (and wal-mart) for about $5, I use one to crush up larger pellets into powder for fry. It does rather well, however, I don't know exactly how it will do against rock...
