Flourite® Black 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® 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. Flourite® Black 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 each 7 kg occupies a volume of approximately 7,000 cm3 (425 cu. in.). To determine your desired volume multiply tank width by length by desired depth.
Directions
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.
NOTE: The specialized mesh bottom of the 3.5 kg size allows it to be rinsed right in the bag.
