Made from stable, porous clay gravel, Flourite provides an ideal root environment while maintaining its structure for the lifetime of your aquarium—without breaking down or requiring replacement.

Setup & Use

Although Flourite is pre-washed, it is a natural substrate and may contain dust from transport. Rinse before use if desired. When filling your aquarium, pour water slowly onto a bowl or plate placed on the substrate to minimise disturbance. Some temporary cloudiness is normal and will clear with mechanical filtration. Seachem Clarity® can be used to accelerate water clarification.
