Seachem Flourite Sand

Flourite® Sand is a specially fractured stable porous clay gravel for the natural planted aquarium. Its appearance is best suited for planted aquariums, but can be used in any freshwater aquarium environment. Flourite® Sand is most effective when used alone as an integral substrate bed, but can be mixed with other gravels. Gravel modifiers such as laterite are not necessary. Flourite® Sand is not coated or chemically treated and will not alter the pH of the water. Flourite® Sand is good for the life of the aquarium and does not need to be replaced.
