Premium natural sand for the planted aquarium
Good for the life of the aquarium
Rinse right in the bag (3.5 kg only)
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 bag (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
TIPS: When adding water to aquarium, fill slowly to avoid disturbing Flourite® Black Sand 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. For an even stronger root zone and enhanced growth rates, add a 2.5 cm (1 inch) base layer of Onyx Sand™ to your aquarium before adding Flourite® Black Sand.
