Eco Complete doesn't isn't really a sand. The grain sizes range from sand like to pea size with a few larger grains here and there. Over time it settles with the smallest particles on the bottom and the largest on the top.
If you want finer grains then Onyx sand might be more to your taste although it's not as dark as eco, but still quite nice looking.
