I have a 75 gallon tank with about an inch of sand as well. I find my 2 strawberry conchs do a fairly decent job. Fighting conchs would do well also. I have some nassarius snails including the orange spotted one and we never see them...so they may aerate the sand but they sure don't turn it over. I also read that the orange spotted one needs actual flesh to feed on or else it will die. Mine's been kicking around since Christmas, so we'll see.
