One of the most important components to maintaining a healthy reef or marine aquarium environment is calcium. Found naturally in seawater, corals and many invertebrates need calcium to build skeletal structures.
Natural seawater contains approximately 420ppm of calcium. Recommended levels of calcium in a closed system should be between 400 and 450ppm. Deferent reef aquariums have different calcium demands depending on the types of corals being supported. It is recommended to dose calcium supplements at night in order to counter the natural tendency for pH to decrease at this time. It is best to dose calcium supplements slowly by using a drip system.
