| Some corals and coralline algae use magnesium, in addition to calcium and strontium, in the formation of skeleton structure. The addition of Tropic Marin Bio-Magnesium to the marine aquarium restores the crucial magnesium/calcium ratio to its natural saltwater concentrations, ensuring optimal skeletal growth. Tropic Marin Bio Magnesium contains no phosphates and nitrates. Recommended maximum dosage: 10 measuring spoon (5 g) on 100 l of water. |
