CoraLazarus

High-purity natural mineral that may be used in traditional calcium reactors or blended in to pre-existing aquarium substrate to gradually increase and maintain the calcium concentration and alkalinity in marine aquaria. Strong source of calcium, the most abundant cation by percent mass in aragonite, the mineral secreted by reef-building organisms to form skeletal material. Through dissolution, provides calcium, magnesium, strontium, potassium, and carbonates. Aids in increasing alkalinity to stabilize pH and encourage rapid biogenic aragonite formation. Optimal average particle size for use in media reactors and calcium reactors. Free of chloride and sulfate. Made in the USA.
