Why is calcium required

Calcium is a major constituent of calcareous algae skeletal material of hard corals and the skeletal needles of softleather corals. Calcium also fulfils many biological functions. These processes result in depletion of calcium. Quite often a too low calcium concentration retards growth of corals and calcareous algae. NSW Natural Sea Water contains 400 450 mgL calcium. This is also the value we should strive for. For a stable aquarium environment the fluctuation in calcium content should not be more than approx. 15 mgL. About Coral Calcium We have highly concentrated this supplement. In fact a higher concentration is impossible to achieve. Each liter contains approx. 160000 mg of calcium. You will appreciate this when you consider that an average aquarium depletes 58 mg of calcium per liter each week. To avoid an ionic imbalance we properly balance the calcium with ions such as sulfate chloride bromide sodium and magnesium. All ingredients are of a pharmaceutical quality or even better. This ensures that no unwanted elements are added to your valuable aquarium. Right after you have dosed this supplement the calcium is immediately for the full 100 available to your corals and other calcium requiring organisms.
