Calcium is indispensable for a natural growing of corals.
The ideal Ca-content of the ocean is abt. 400-450mg / liter.

Dosing quantity:
1 ml Calcium pro liquid contains 250 mg immediately available Calcium.
That means 10ml calcium pro liquid increases the calcium value by 25mg/l to 100 l aquarium water
A rise of the calcium value in the aquarium should take place slowly and over several days.

With addition of Calcium pro liquidt the kH-value in the aquarium is lowered.
The kH-value reflects the pH-buffer volume of the water. In case of a too low kH-value, there will be the danger of a pH-drop.
For the increase of the kH value and/or preservation of the pH value please use kH+Ca 1 or Carbonat pro instant.
