Product:
Strontium plays an important role due to faster growth of coral and calcareous algae.
Natural seawater contains approx. 7-9 mg / L strontium. Since the growth of corals and lime algae goes hand in hand with strontium and calcium depletion, depletion of calcium usually means depletion of strontium.

It is advisable to use a strontium concentration between 5 and 20 mg / L.
Ca. 25 tests per kit. Scale distribution 5 ppm

Note:
Keep out of the reach of children! Only for aquarium hobby use.
