Accurate Calcium Monitoring

Calcium is one of the primary elements used by corals and other calcifying organisms to build their skeletons. Regular testing helps ensure calcium remains stable and allows you to adjust dosing based on your aquarium's actual consumption.

The Calcium Pro test provides a resolution of 5 ppm, making it suitable for monitoring reef systems where accurate calcium management is important.
