Product: Seachem Flourite Black 3,5 kg
Flourite BlackTM 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 BlackTM 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 BlackTM is not chemically coated or treated and will not alter the pH of the water.
Although pre-washed, it may be rinsed before the use to remove residual dust. Dust can be minimized by filling aquarium slowly and dispersing water so that the Flourite BlackTM bed is not disturbed. Slight initial cloudiness is normal and will clear rapidly (2 - 12 hours). To shorten the cloudiness period use ClarityTM in conjunction with mechanical filtration (such as filter floss).
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 (325 cu. in.). To determine your desired volume multiply tank width by length by desired depth.
