Its appearance is best suited to planted aquaria, but may be used in any freshwater aquarium environment. Flourite Black Sand is most effective when used alone as an integral substrate bed, but it may be mixed with other gravels. Gravel modifiers such as laterite are not necessary. Flourite Black Sand is not chemically coated or treated
