Seachem Flourite Dark 7kg | Premium Natural Dark Planted Aquarium Substrate

Create a stunning natural aquascape with Seachem Flourite Dark 7kg, a premium porous clay substrate specifically designed for planted freshwater aquariums. Featuring a rich dark colour, Flourite Dark enhances the vibrant colours of aquatic plants and fish while providing an excellent environment for strong, healthy root development.

Unlike nutrient-rich aquasoils that gradually break down, Flourite Dark is a stable, porous clay gravel that retains its structure for the life of the aquarium. It is not chemically coated or treated, will not alter your aquarium's pH or water chemistry, and never requires replacement, making it a long-term investment for planted aquariums of any size.

Setup & Use

Although Flourite Dark is pre-washed, it is a natural product and may contain some dust from transport. A light rinse before use is recommended.

When filling your aquarium, pour water slowly over a plate or bowl placed on the substrate to avoid disturbing the substrate bed. Some temporary cloudiness is normal and will clear with mechanical filtration. For faster clearing, Seachem Clarity® can be used alongside fine filter media.
