Tropic Marin Bio-Magnesium 450g
The ongoing growth and health of stony corals is as directly linked to a continued supply of magnesium and strontium as it is to the supply of biologically available calcium.
Both the absolute concentrations and the concentrations of these elements relative to each other change rapidly in the reef aquarium. This is due to the absorption of these elements for the stony skeletal structure of the corals and also due to natural precipitation.
Just as Bio-Calcium has been proven to supply the most natural, biologically available form of calcium to marine aquaria for years, Tropic Marin's new Bio-Magnesium and Bio-Strontium do the same for magnesium and strontium respectively.
