Flourite™ 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™ 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™ is not chemically coated or treated and will not alter the pH of the water. Although pre-washed, it should be rinsed before use to remove residual dust. Dust can also be minimized by filling tank slowly and dispersing water so that the Flourite™ bed is not disturbed. Slight initial cloudiness is normal and will clear rapidly (2–12 hours). This bag is sufficient for about a 5 cm (2 inch) deep bed in a typical 40 L (10 gallon) tank. Recommended use is 1 kg (2 lbs) for approximately each 200 cm2 (31 in2) of tank bottom at a depth of 5 cm (2 in).
