Calcium is a major constituent of calcareous algae, skeletal material of hard corals and the skeletal needles of soft/leather corals. Calcium also fulfils many biological functions. Quite often, a too low calcium concentration retards coral and calcareous algae growth.
To maintain a stable environment it is important that the calcium content should not fluctuate by more than 15 mg/L from the optimum range of 420 - 450 mg/L. This automatically means that the calcium test should be able to monitor comparable fluctuations.
Salifert calcium test is capable in resolving the calcium content in 10 mg/L steps. The colour change is sharp and facilitates the detection of small but highly significant fluctuations in the calcium concentration. Salifert is the only one in offering a true accuracy and precision as claimed. The kit can perform approx. 50 - 100 measurements.
