Seachem – Flourite Black Sand™
Flourite Black Sand™ is a specially fracted, stable porous clay substrate for the natural planted aquarium. Its appearance is best suited to planted aquaria, but may be used in any aquarium environment. It s most effective when used alone as an integral substrate bed, but it may be mixed with other gravels and sand. Substrate modifiers such as laterite are not necessary. As it is not chemically coated or treated, it will not alter the pH of the water.
Although pre-washed, it may be rinsed before use to remove residual dust. Dust can also be minimized by filling aquarium slowly and dispersing water so that the substrate bed is not disturbed. Slight initial cloudiness is normal and will clear rapidly (2–12 hours).
