Bio-Balls are the best way to allow your reptiles to drink from their water bowl without allowing insect prey to drown in them, thus fowling up the water supply and creating a 'big stink.' The balls allow for ample drinking but also give insects something to climb on to so that they may escape from the water bowl before they drown. Stop that terrible stink from dead crickets and other insect prey items drowned in your water dish.
