Flourite® Black Sand 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 Sand 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 Sand is not chemically coated or treated and will not alter the pH of the water. Flourite® Black Sand 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, 15.4 lbs occupies a volume of approximately 5,500 cm³ (320 cu. in.). To determine your desired volume multiply tank width by length by desired depth.

Directions

Although it is pre-washed, because Flourite® Black Sand is a natural product, it may become dusty in transit and require rinsing before use to remove any residual dust.
