Need Magnesium - Ultra Mag
 

Calcium- and magnesium granulate based on dolomite applicable for Calcium Reactors for CO2 binding and magnesium enrichment. ULTRA MAG automatically releases magnesium to the water to stabilize the magnesium concentration in sea water. As the material binds CO2 a uncontrolled increase in free dissolved CO2 is avoided.
