Lava Rock Gravel may be used for a wide variety of purposes. We recommend using it as an accent to a Black Lava Rock aquarium hardscape layout, filtration media, or as a tank substrate! The possibilities are endless! This lava rock gravel is inert and will not change water parameters.
Black Lava Rock is a classic aquascaping stone that's often used in all types of aquarium setups such as planted tanks, freshwater, and brackish. Because of its highly porous nature, easy aquatic plants like moss, Anubias, Ferns, and Bucephalandra will readily attach themselves to these rocks. In addition, it's also great for the colonization of beneficial bacteria resulting in a healthier aquarium environment.
