Seachem Flourite Black – Natural Porous Substrate for Planted Aquariums (7kg)

Seachem Flourite Black is a especially fracted, stable porous clay gravel that provides an ideal substrate for rooted aquatic plants. Its dark, natural appearance enhances the visual appeal of aquascapes while supporting healthy root development and nutrient uptake.

Unlike coated or chemically treated substrates, Flourite Black is completely inert and will not alter the pH or hardness of your aquarium water. It is rich in iron and other trace minerals, eliminating the need for additional gravel modifiers such as laterite. It can be used alone or mixed with other substrates and is compatible with under gravel filters.
