Create a striking, nutrient-rich foundation for your aquatic plants with Seachem Flourite Black. Specially porous and clay-based, this premium natural gravel is designed specifically for natural planted aquariums. Unlike traditional substrates that break down over time, Flourite Black never softens, degrades, or requires replacement—remaining effective for the lifetime of your aquarium. Its deep black tone enhances the rich greens and reds of living plants while creating a high-contrast backdrop that highlights the natural colors of your fish and invertebrates. Safe for all freshwater ecosystems, it contains no chemical coatings and will not alter your tank's pH parameters.
