Use nassarius snails instead. A refugium is too small for a sand sifting star in most cases. Also they will inhibit the sand bed from denitrification to a degree by consuming microfuana.
Cerith snails will also stir up the sand some, but need more than if they were nassarius snails.
Stirring up the top inch or so weekly during a water change will do the same thing also. Invert free.
