Calcium is a macro element which is present in abundance in reefs around the world. All animals present in our aquariums need calcium along with carbonate, they use it to support their vital functions and grow. It is crucial to supply our tanks with a stable level of calcium.
Calcium is a macro element that gets depleted from the water in our tanks very quickly. Therefore, it is important to dose calcium in a stable and constant way. Calcium levels should be checked regularly and adjusted to ensure optimal levels i.e. between 380-450 mg/l.
Calcium Zlement used in conjunction with a regular testing procedure, allows any reefer to make corrections to their tank Calcium levels ensuring their water levels stay within the best range for their friends.
10 ml of Calcium Zlement increase the Calcium concentration of 100 litres by 20 mg/l.
