Deltec USA Aquatic Calcite Media 8-16mm is a raw, naturally returning, biogenic, 99.8% pure calcium carbonate derived from marine aragonite. Its near chemical purity and size consistency make it the complete reactor media for all calcium reactors. Containing not only calcium and carbonates, but also essential trace elements such as strontium, magnesium, molybdenum and potassium. Due to its high solubility, CO2 consumption significantly reduces. Another advantage is the lack of nitrate, phosphates, and silica, which prevents diatom blooms in the aquarium.
5.5kg per bag.
