Seachem Flourite Red 3.5kg
Flourite Red™ 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 Red™ 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 and unlike competing products, Flourite Red™ never has to be replaced. It remains effective for the life of the aquarium. Flourite Red™ is not chemically coated or treated and will not alter the pH of the water.
