Features in common: both of the coral bone sands are natural grown material, porous structure make them perfect medias to foster nitrobacteria and filter out impurities in aquarium water.
Differences: The normal coral bone is of higher rate of decay, so its color is darker and has more sand and less holes compared to the premium one. But it is also cost-effective due to its cheaper price.
Easy-to-use and has wide applications.
