Ideal for salt water aquariums and coral reef tanks. Designed to measure calcium in reef tanks, the Hanna Calcium Checker is perfect for corals and marine life. This Checker®HC from Hanna instruments is supplied with reagents for 25 tests.

Corals need an adequate level of calcium in the water to support healthy growth: if levels are too low, corals cannot  form their skeletons; if levels fluctuate too much or too quickly, growth can become impaired. The more precise and stable the levels, the better the results. With regular, precise monitoring, fluctuations in levels can be quickly corrected, giving your corals the best chance of success.
