I can tell you the chips no matter how small are very sharp. I personally dont think it is a safe material/natural to use it could do some damage to some fish who like to pick up a mouthful of the base looking for food. Keith Near enough is not good enough, therefore good enough is not near enough, and only your best will do. I VOTE DO YOU if not WHY NOT? VOTE NOW VOTE NOW
