Magnesium plays an important role in maintaining appropriate calcium and alkalinity levels, by enabling these elements to stay in solution at the higher than normal levels found in Natural Sea Water. TheReef® Magnesium liquid supplement contains pure magnesium salts that can be readily taken up by corals and other marine organisms. Guidance: First measure magnesium levels in your aquarium with an accurate test kit to determine how much of the supplement you should add. Natural Sea Water values for magnesium are around 1300ppm while 15ml (1 capful) of TheReef® Magnesium supplement per 100 litres of aquarium water will raise magnesium levels by around 10ppm. Shake bottle before use then add required quantity of supplement to an area of aquarium or sump with high flow. Do not raise levels by more than 50ppm a day. Do not mix with or use within 1 hour of alkalinity, boron or other carbonate type additives and supplements. Store above 10°C.
