Magnesium and calcium must be present in a balanced ratio for the optimal growth of corals and other invertebrates. The magnesium level should not be below 1,300 mg/l (ppm). The sera Mg-Test kit provides information about the magnesium level.

Use the cap as a measure.
Add one capful sera marin 6 for every 100 liters (26.4 US gal.) of aquarium water. Always add sera marin 6 after having raised the calcium level with sera marin 1 and 2.
