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.

Our 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.
