Calcium is a major constituent in your marine aquarium with concentrations around 410-450ppm. Strontium is a minor constituent with suggested concentrations of around 8ppm. These levels must be maintained to help with the function of fish, coral and many other wanted inhabitants. Calcium and Strontium are taken up within specific ratios; these ratios were tested by Ph.D graduates using instruments such as Atomic Absorption Spectrometers (AAS). The ratio uptake of Strontium to Calcium is very important and the “Calcium/Strontium Coral Skeleton Ionic Ratio” supplement has very similar concentrations of both ions derived from these findings.
