Often in tabletop crokinole play, the "sand" isn't even used. Modern boards are often slick enough to get away with playing without it, and if it's a board that you roll out regularly, you may not want the cleanup overhead associated with using shuffleboard "sand."

Also note that you'd never use actual sand on a crokinole board or tabletop shuffleboard. Sand, wax, or powder is what the shuffleboard products are referred to as and are made of specially formulated silicone beads (much less abrasive than, say, beach sand) or cornmeal, or even sometimes ground walnut shells.
