Sachem fluorite 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. Fluorite 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. Fluorite is not chemically coated or Treated and will not alter the pH of the water. Fluorite is good for the life of the aquarium and need not be replaced.
