Seachem Flourite Black Sand 3.5kg Premium Natural Gravel for the Planted Aquarium

Flourite® Black Sand, a specially fracted stable porous clay gravel, excels in natural planted aquariums. Its appearance suits planted aquaria well, but it also fits any freshwater aquarium. Using Flourite® Black Sand alone as the primary substrate bed maximises its effectiveness, though mixing it with other gravels is also an option. You don’t need gravel modifiers like laterite. This product, free from chemical coatings or treatments, does not change the water’s pH. Flourite® Black Sand remains effective for the aquarium’s entire lifespan and doesn’t require replacement.

Despite pre-washing, Flourite® Black Sand, being natural, can gather dust in transit and may need a rinse before use to remove any residual dust.

To add water to the aquarium without disturbing the Flourite® Black Sand bed, do so gently. Place a bowl in the aquarium, add water to it, and let it overflow softly onto the gravel bed. Expect some initial cloudiness. Clear this by using mechanical filtration methods, like filter floss, or use Clarity™ to hasten the clearing process.
