I always mix 1/2 sugar grain sand, with 1/2 of the larger size, can't remember what they call it. Doesn't look as nice, but it gives digging animals the chance to build burrows and stuff easier, they dont collapse.

Put the seio a little lower in the tank, and point it upwards towards the middle of the tank. This will break up the surface nicely for you too, otherwise organics will collect there and form a little "skin" of oils and stuff.
