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. 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. Dosage should be established basing on water tests and daily corals consumption. Before applying Mg Plus it is recommended to test magnesium level in the water. We do not recommend raising magnesium levels by more than 50 ppm a day. Please ensure your magnesium level is within the recommended range before attempting to raise or adjust your calcium and alkalinity levels.
Worth knowing: The product can be used only in the aquarium. Not suitable for human consumption. Keep out of the reach of children.
