Highly concentrated solution for adding calcium if there are deficits in the aquarium.
Calcium is an alkaline earth metal and one of the most important skeletal components of numerous vertebrate and invertebrate skeletons and has important metabolic functions. It is always an integral part of the calcium supply system in the aquarium and forms the basis for coral growth. The coral combines calcium with carbonates to form solid lime, calcium carbonate. It is found in the sea in concentration levels of 400 - 440 mg/l (ppm).
