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.
Quite often a too low calcium concentration retards coral and calcareous algae
growth.
NSW contains 400 – 450 mg/L calcium. Which is also the value we should strive
for. For a stable aquarium environment the fluctuation in calcium content should
preferably not more than approx. 15 mg/L. This automatically means that the
calcium test should be able to monitor comparable fluctuations.
In a healthy aquarium growth and multiplication of corals, desired calcareous
algae and other organisms results in calcium depletion. Because of the
importance of calcium timely corrective measures would have to be taken. For
that purpose a proper calcium additive together with an accurate test kit are
required.
The calcium test is capable in resolving the calcium content in 10 mg/L steps.
The color 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.
