Highly concentrated formula for raising magnesium levels in marine aquariums.
Magnesium is necessary for healthy and balanced growth of corals.
The appropriate level of magnesium in the tank water provides corals better absorption of calcium. Reduced level of magnesium may cause inability to maintain proper calcium level and lowered pH.
Mg Plus is used for managing shortages and sudden drops of magnesium levels Recommended magnesium level in reef aquariums is 1180-1460 mg/l (ppm).
Dosage: 
10 ml of Magnesium solution raises magnesium level by 7.5 mg/l (ppm) in 100 l (27 US gal) of water.
