Magnesium is the third most important element in the composition of seawater. It is essential for many biological processes, such as photosynthesis and cell division. It is also used in the formation of the skeleton of reef organisms. Levels of 1200 to 1380 ppm are desirable to maintain a healthy environment for your corals.

Instructions: Shake well before use. Standard dose: 1 bottle per 200 liters (50 gallons) of seawater per week. Dose to increase concentration: 1 vial per 100 liters (25 gallons) of seawater. A weekly change of 10-20% of the water with Reef Evolution salt is strongly recommended to maintain optimum water quality. When adding the product, pour gently into the current to ensure even distribution. Allow 5 minutes between additions of any other product. Do not mix different products before dosing. Direct contact with marine organisms should be avoided, as high local concentrations can be harmful. Like all chemical products, it should be kept out of the reach of children.
