Black Lava Rock is an essential aquascaping stone that's often used in all types of aquarium setups such as planted tanks, freshwater, and brackish aquariums. Loved for its pourous texture, you will commonly see Black Lava Rock paired with epiphytic aquarium plants and aquatic or terrestrial mosses. Black Lava Rock also makes a great base for moss-covered stones as an accent to any aquascape since it is typically available in smaller sizes. Easy aquatic plants such as Anubias, Bucephalandra and fern plants will also self-attach rather quickly. Another benefit of having Black Lava Rock in a tank is its ideal habitat for the colonization of beneficial bacteria resulting in a healthier aquarium environment. The best thing about Black Lava Rock is that due to its relatively lightweight, you'll get more volume per pound.

How many pounds do I need?
We advise 2 x Tank volume in gallons = Total amount of pounds required

TIP: Take advantage of Lava Stone's porous texture! It provides a perfect surface for delicate aquarium mosses to grow on. We like Mini Pellia and Fissidens Fontanus!
