Flourite Black (for plants)

Seachem Flourite Black is a very high-quality substrate. It is composed of porous, stable, and specially graded clay gravel, designed specifically for natural planted aquariums. This mineral-rich gravel has a beautiful deep black color. It is neither chemically treated nor coated, and does not alter the delicate pH balance of the aquarium. It is most effective when used alone, but can also be mixed with other types of substrates without negative reaction.
