Flourite Red Aquarium Substrate 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 Red 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 Red is not chemically coated or treated and will not alter the pH of the water. Flourite Red is good for the life of the aquarium and need not be replaced.
INSTRUCTIONS: Although it is pre-washed, because Flourite Black is a natural product, it may become dusty in transit and require rinsing before use to remove any residual dust. When adding water to your aquarium, fill slowly to avoid disturbing Flourite substrate bed. Place a bowl in the aquarium and add water directly to the bowl, allowing water to overflow softly on to the gravel bed. Initial cloudiness is normal. To remove cloudiness, use mechanical filtration (such as filter floss).
