Black lava stone is an essential aquascaping stone that is commonly used in a variety of aquarium setups such as planted tanks, freshwater, and saltwater aquariums. Black lava stone is popular for its porous texture and you will often see it paired with epiphytic aquarium plants and aquatic or terrestrial mosses. Black lava stone is also a great base for moss covered stones to accent any aquascape as it is usually available in smaller sizes. Another benefit of having black lava stone in your aquarium is that it is an ideal habitat for beneficial bacteria to colonize, thus creating a healthier aquarium environment.
