I got a sample of Soil Master Select from Ken, and it is identical in size, shape and color to the Turface. Actually, the SMS sample contained more bits of red clay mixed with the gray, so I think the Turface may actually be more uniform in color than the SMS. I am not sure about the dust factor, but after some rinsing, and letting it settle a couple hours, the Turface looks great and the water is not cloudy. I have several bags at this point, but just put an ad on Craig's List.
