Salifert’s Calcium Profi Test Kit can provide between 50 and 100 tests – helping you to monitor the calcium levels within your aquarium. Calcium is fundamentally import to marine inverts and a constituent of coralline algae, so make sure you have a sufficient level.
Calcium is a major constituent of coralline algae, the skeletal material of hard corals and the skeletal needles of soft/leather corals. In many cases too low a calcium concentration retards coral and coralline algae growth. Calcium also fulfils many important biological functions.
In a healthy aquarium, the growth and multiplication of corals, calcareous algae and other organisms can result in calcium depletion. 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 so regular testing should be carried out.
This means that any calcium test used should have an accuracy of significantly less than 15mg/L otherwise it will be difficult to monitor such fluctuations.
The Salifert test kit measures in steps of 5 mg/L and has an accuracy of 10 mg/L.
The colour change is precise, detecting small but significant fluctuations in the concentration of calcium.
The test is not affected by magnesium.
Saliferts Coral Calcium additive is a highly concentrated additive which makes calcium addition easy.
Sufficient for at least 50 tests
