Seachem Flourite Black is a specially fracted stable porous clay gravel for the natural planted aquarium. Its appearance is best suited to planted aquariums, but may be used in any freshwater aquarium environment. Flourite Black 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 Black is not chemically coated or treated and will not alter the pH of the water. It is good for the life of the aquarium and need not be replaced.
To determine the number of bags required for your aquarium, please note that 7kg of Seachem Flourite Black occupies a volume of approximately 5,500cm3. To determine your desired volume multiply tank width by length by desired depth.
Although it is pre-washed, because Flourite is a natural product, it may become dusty in transit and require rinsing before use to remove any residual dust.
The specialized mesh bottom of the 3.5kg size allows it to be rinsed right in the bag.
When adding water to aquarium, fill slowly to avoid disturbing Flourite Black 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. For an even stronger root zone and enhanced growth rates, add a 2.5cm base layer of Seachem Onyx Sand to your aquarium before adding Seachem Flourite Black.
