I initially bought washed construction sand which was medium course. Since then I've added courser sand with pebbles in it, and finer sand, like sand dune sand. I can't say that I've really noticed any benefits of one over the other. It's all mixed together now. When I get (shovel into buckets) more at the local lake, I will probably go for the finer stuff from now on as it seems to clump a little better and I won't end up scooping pebbles when I scoop the poo.
