CHILLERS & HEATERS
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. Flourite® Black 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 is not chemically coated or treated and will not alter the pH of the water. Flourite® Black is good for the life of the aquarium and need not be replaced.
Although it is pre-washed, because Flourite® Black is a natural product, it may become dusty in transit and require rinsing before use to remove any residual dust.
When adding water to 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. To remove cloudiness, use mechanical filtration (such as filter floss). Use Clarity™ to accelerate clearing.
Service was pretty good, but the bag came damaged , appeared like already damaged bag was sent as very little substrate was there in box , when weighed only 6820g was there, I didn’t knew that I could claim for the damage so I didn’t took pics of bag , seller was very good told me if I had taken pictures I could have claimed for the damage , product was shipped from some other location than his so it was fault of some other person
