The highest concentrated formula for raising magnesium levels in marine aquariums. Mg Plus is created for managing shortages and sudden drops of magnesium levels. 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. A reduced level of magnesium may cause an inability to maintain proper calcium levels and a lowered pH. The recommended magnesium level in reef aquariums is 1180 – 1460 mg/l (ppm).
Dosage
10 ml of Mg Plus raises magnesium level by 10 mg/l (ppm) in 100 l (27 US gal) of water.
Dosage should be established based on water tests and daily coral consumption. 
Please remember, that maximum safe daily dose is 100 ml per 100 litres of water. If you need a higher dose, split it into a few days.
We recommend using a dosing pump to dose the magnesium solution slowly throughout the day.
Before applying Mg Plus it is recommended to test magnesium levels in the water. 
We do not recommend raising magnesium levels by more than 100 ppm a day. 
Please ensure your magnesium level is within the recommended range before attempting to raise or adjust your calcium and alkalinity levels.
