PREPARATION: We recommend that you rinse them well, then steep them in boiling (ore really hot) water for 10 minutes or so prior to use, and/or soak overnight in fresh water, which will help soften them a bit, and make them more palatable to shrimp, as well as to foster a "biofilm" on their surfaces, which provides supplemental grazing for shrimp and small fishes, and fry.
