Calcium is a major constituent of calcareous algae, skeletal material of hard corals, and the skeletal needles of soft/leather corals. Calcium also fulfills many biological functions.
400 – 450 mg/L calcium is the value we should strive for. For a stable aquarium environment, the fluctuation in calcium content should preferably not be more than approx. 15 mg/L. This automatically means that the calcium test should be able to monitor comparable fluctuations.
The kit can perform approx. 50 - 100 measurements.
