Salifert® Calcium Ca Profi Test Set for the accurate determination of the calcium content in water.

Calcium is a major component of calcareous algae, skeletal material of hard corals and the skeletal needles of soft/leather corals. Calcium also performs many biological functions.

Too low a calcium concentration often inhibits the growth of corals and calcareous algae.

Natural seawater contains 400 - 450 mg/L calcium. This is also the value we should aim for. For a stable aquarium environment, the fluctuation in calcium content should not exceed about 15 mg/L if possible. This automatically means that the Salifert® Calcium Ca Profi calcium test should be able to monitor comparable fluctuations.

However, Salifert® Calcium Ca Profi can of course also be used to measure Ca in freshwater tanks.


In a healthy aquarium, the growth and proliferation of corals, desired calcareous algae and other organisms leads to a depletion of calcium. Because of the importance of calcium, timely countermeasures would need to be taken. This requires a suitable calcium supplement along with an accurate test kit.

Our calcium test is capable of resolving calcium levels in 10 mg/L increments. The color change is sharp and facilitates the detection of small but highly significant variations in calcium concentration. Salifert is the only one to offer true accuracy and precision as claimed.

Approximately 50 - 100 measurements can be taken with the Salifert® Calcium Ca Profi Kit.

The Coral Calcium additive from Salifert is produced using a very special process. The result is a highly concentrated additive that not only facilitates the addition of calcium, but also prevents the ion balance from being disturbed when used in combination with our KH + pH buffer or another sodium-based buffer. Conventional additives containing only calcium chloride or the improper use of lime water (calcium hydroxide) can disturb the ionic balance, resulting in aquarium water that is very different from natural seawater.
