Highly concentrated solution for adding strontium if there are deficits in the aquarium.
As an alkaline earth metal, strontium is essential for skeletal growth in stony corals and calcareous red algae. If concentrations are too low, this can impair the color and growth of stony corals and calcareous red algae. It is found in the sea in concentration levels of approx. 8 mg/l (ppm).
