Flourite dark 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 aquarium environment. Flourite dark 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 dark is not chemically coated or treated and will not alter the pH of the water. Although it is pre-washed, because Flourite® Dark is a natural product, it will become dusty in transit and require thorough rinsing before use to remove any residual dust ( rinse until water runs clear through substrate). When adding water to aquarium, fill slowly to avoid disturbing Flourite® Dark 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). Use Clarity™ to accelerate clearing.
No laterite needed
