Salifert Calcium Test Kit.
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.
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.

Best Budget Calcium Test kit available Review by Mitch
I like using Salifert test kits. I find they are very reliable and accurate. This is a bargain. For $20 you get about 50 tests for Calcium. This is important test for reef tanks. If I keep my Calcium levels too low, my corals suffer. Once I get the calcium levels to around 450-460 ppm, the corals look much healthier and have better color. (Posted on 7/9/2014)
Good test Review by Ben
I am very pleased with this test kit. The color change is sharper than other calcium tests Ive tried and the measurements are more accurate. It has a couple more steps to perform the test than other types, but that what makes it more accurate. I also like that it has instructions for "halving" the test so you can get double the tests out of the reagents. (Posted on 9/25/2009)
