Aquaforest Magnesium provides an easy to use agent for raising magnesium levels in reef aquariums. Magnesium is essential for the proper development of corals. Lowered magnesium levels may cause inability to maintain proper calcium level and too low pH. The recommended level of magnesium in reef aquaria is 1180-1460mg/l (ppm).

Dissolve 10g in 1Ltr RODI water. Dosage should be determined by your water test results and corals daily consumption. Before applying Aquaforest Magnesium solution into the water, it is recommended to run a water test to check current water parameters. 100ml of Magnesium solution in 100L of water raises Magnesium level by 1,2mg/l (ppm). We do not recommend raising Magnesium level by more than 50ppm daily. In order to maintain ionic balance KH Buffer and Reef Mineral Salt should also be applied. Magnesium and Calcium or Reef Mineral Salt can be combined together into one solution. Contains MgCl2x6H2O.
