Plants anchor themselves more easily, even with fine roots, which helps achieve faster and more vigorous growth . This substrate also limits compaction, reduces stagnant areas, and encourages the colonization of beneficial bacteria , essential for the biological balance of the tank. Its rounded shape also provides a natural appearance and protects bottom-dwelling fish. It's a solid foundation for a clean, balanced, and enjoyable planted aquarium.
