Aquarium Substrate

Aquarium substrate consists of materials used as a base in freshwater or saltwater aquariums. Freshwater aquariums can have freshwater gravels, plant substrates, and sand to make up the aquarium base. Marine aquariums usually use sand and gravel. The type of substrate needed for the aquarium depends greatly on the type of set up you want and the type of fish you are going to keep. Some fish are fine with a harsh substrate, while others need something that is fine in order to prevent injuries when swimming along the bottom of the aquarium.
