Strontium Test Salifert Strontium plays an important role by accelerating coral and calcareous algae growth. NSW contains approx. 7 – 9 mg/L strontium. Since the growth of corals and calcareous algae goes hand in hand with strontium and calcium depletion, depletion of calcium usually means depletion of strontium as well.
