Product description

• GRAVEL Seachem 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.
• AQUARIUM BED Gravel modifiers such as laterite are not necessary when using Seachem Flourite Black as this product is most effective when used alone as an integral substrate bed, but it may be mixed with other gravels.
• SET-UP When adding water to the aquarium, fill slowly to avoid disturbing Flourite Black 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, but to remove this simply use mechanical filtration
• COMPATIBLE Flourite Black substrates will work fine with an under gravel filter and will not soften or decompose to an unsuitable state within your tank.Flourite substrates will work fine with an UGF
• SAFETY Seachem Flourite Black is not chemically coated or treated, thus does not alter the pH of the water. Flourite Black is beneficial for the life of the aquarium and need not be replaced.
