Decorative Black Basalt Gravel for Aquariums and Drainage

Discover a gravel of volcanic origin, 100% natural and free of additives or coatings, ideal as a substrate for aquariums and as a decorative element in gardening and landscaping. Its inert composition behaves neutrally in water, does not alter the parameters and does not release unwanted substances, guaranteeing a safe environment for fish, invertebrates and plants.

Thanks to its deep tone, it creates elegant contrasts that enhance the underwater landscape, providing a modern and clean look to the aquarium. Rich in trace elements, it promotes rooting and vigorous growth of aquatic plants, and is especially suitable for shy species that feel safer with dark-looking substrates.

Its homogeneous texture facilitates water circulation between grains, minimizes compaction and helps prevent anaerobic zones, while providing a stable base for hardscape. Plus, it looks just as good dry as it does wet, so it's also perfect for decks, walkways, pots, and other outdoor landscaping projects.
