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 and will not alter the pH of the water. Flourite Black Sand is good for the life of the aquarium and need not be replaced.
