Black lava rock is used in all kinds of aquariums due to its plant growth benefits. This volcanic rock has countless tiny holes and crevices—and this creates an extensive surface area per volume ratio. What does this mean for your plants? Well, it makes way for processes that contribute to healthier and more robust plant life within the aquatic environment.
It serves as an excellent substrate for anchoring aquatic plants securely, allowing them to establish their root systems effectively. The rough texture also provides adequate grip for delicate-rooted species, preventing them from becoming uprooted and damaged during cleaning.
