Flourite? is a specially fracted stable porous clay gravel for the natural planted aquarium. Its appearance is best suited to planted aquaria but may be used in any freshwater aquarium environment. Flourite? 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? is not chemically coated or treated and will not alter the pH of the water. Flourite? is good for the life of the aquarium and need not be replaced.
