Natural Gravel

Natural gravel works to promote better health for your fish, corals, shrimp, plants, and other aquatic species. Our aquarium gravel consists of substrate with small stones, such as Black Diamond substrate or Super Naturals Blue Ridge Premium substrate. Our natural gravel is excellent for certain fish species like the catfish.

One of the many benefits of natural gravel is the smooth surfaces which help to protect fish from accidental injury. In addition, most of our substrates contain calcium, iron, magnesium, potassium, and over 25 other natural gravel substrate elements. These help to ensure your fish and plants receive the proper nourishment. Please browse our natural gravel options for more information or contact us today.
