Superior Supplement for Reef Tanks.Features: Makes High Calcium Concentration and Alkalinity Possible. Promotes Growth of all Invertebrates. Superior Purity. Free Convenient Measuring Device Included. Why Magnesium is Required:Magnesium is present in NSW (Natural Sea Water) in a fairly high concentration (1350 - 1500 mg/L). Magnesium is an essential part of chlorophyll, which is necessary for photosynthesis. Without photosynthesis algae and hence the corals, which we have in our aquariums, would not survive.Magnesium also has another important function in that it allows maintaining the correct combination of calcium concentration and alkalinity or carbonate hardness possible. Maintaining a correct magnesium concentration is therefore very important and is indirectly responsible for fast coral and calcareous algae growth.Magnesium is depleted by algae growth and also by the use of excessive kalkwasser or by going far beyond natural calcium, alkalinity and pH values.Salifert Liquid Magnesium is a highly concentrated supplement. Each liter contains approx. 25,000 mg of magnesium. To avoid an ionic imbalance, Salifert properly balances the magnesium with ions such as sulfate, chloride, bromide, sodium and calcium. All ingredients are of a pharmaceutical quality or even better. This ensures that no unwanted elements are added to your aquarium.Other Requirements: This supplement is intended to be used on a regular maintenance basis. If the magnesium concentration is significantly lower than 1,350 mg/L, Salifert advises to use their Magnesium Powder. This powder is far more effective in raising the magnesium concentration yet is not ionically balanced to the extent of this supplement. The powder should therefore be used as a one time major corrective measure.Directions: Shake before use. Dose 5 mL per 100 Liters (25 gallons) once a week. Adjust dosage according to individual requirements (use a magnesium test, e.g., Salifert's Magnesium Profit-Test). Every 5 mL per 10 Liters (2.5 gallons) will increase the magnesium concentration by approx. 12.5 mg/L (12.5 ppm). Never increase the magnesium concentration by more than 50 mg/L a day. Maintain a magnesium concentration of 1,350 - 1,500 mg/L.Active Ingredients: Sulfate, bromide and chloride salts of magnesium, calcium and sodium.Size: 250 mL (8.45 fl. oz.)
