Create a realistic aquascape in your aquarium with Aqua Gem decorative gravel. The Coral Sand is applicable to the water tank and used for partial hard acidification of the fish tank, it can be applied as filter material and fish tank bottom sand, with the cultivation of nitrifying bacteria, helps improve water quality and PH value. Coral Bone Gravel is coral or shell fragments that can continuously enrich aquarium water with calcium carbonate. Because of its alkaline content, through its filtered pH is generally 7.0 ~ 8.5, the release of calcium ions, magnesium ions to the sea or freshwater, provides a higher hardness and pH stability for aquarium biological surviving. Due to its rich pore structure, as a biological filtration system carrier, a large number of nitrifying bacteria can be breed in it.
Suitable for freshwater, tropical and salt water marine reef aquariums.
