For the determination of the calcium concentration in saltwater.

Calcium is one of the most important components of saltwater and largely determines the growth rate of organisms, which form calcareous skeletons like, for example stony corals and calcareous algae. In the saltwater aquarium, a regular addition of calcium ions is necessary because of the constant decrease of the calcium concentration caused by the metabolism of the organisms and by precipitation.
Careful supervision of the calcium content in the saltwater aquarium ensures optimal and lifelike living conditions for all calcareous organisms.

With a sensitivity of 4 mg/l, the Calcium-Test by Tropic Marin is the most accurate calcium test available. Special reagents intentionally make use of the high magnesium concentration of the saltwater, which usually interferes with aquarium calcium tests, and thus guarantee the outstanding dependability of the results.
