Description Tropic Marin Pro-Coral Mineral Crystallized trace elements for the health and growth of all invertebrates. In a marine aquarium with a large invertebrate bio-mass, particularly of stony corals, trace elements in the water are quickly depleted. At the same time the concentration of macro-elements, such as sodium, chlorine and sulphate, continues to remain constant. Product Features: Contains a concentrated supply of all 70 trace elements found in natural seawater. For color intensity, health and growth of invertebrates. Includes iodine and strontium. Does not contain chelates, phosphates or nitrates. Instructions For Use: Fill the enclosed measuring spoon with Tropic Marin Pro-Coral Mineral (levelling spatula is included). Tropic Marin Pro-Coral Mineral should be added in the filter/sump area of the aquarium at a sufficient distance from the pump, in order to prevent any undissolved crystals from coming into contact with the coral. Alternatively, a concentrated solution can also be prepared with softened water (10 g/2 scoops of powder per liter / per 0.26 US Gal. / per 0.22 Imp.Gal. of water; dosage: 1 liter / 0.26 US Gal. / 0.22 Imp.Gal. of solution per 100 liters / 26 US Gal. / 22 Imp.Gal. of tank water each week). Clouding of the concentration during this process has no adverse effects. Dosage: 5 g (approx. 1 level measuring spoon) is added each week per 50 litres / 13 US Gal. / 11 Imp. Gal. of aquarium water. This increases the proportion of iodine to approx. 0.075 mg per litre and strontium to approx. 1.5 mg per litre. One can is sufficient for approx. 2,500 litres / 660 US Gal. / 550 Imp.Gal.. The recommended maximum dosage is 2 measuring spoons a week per 50 litres / 13 US Gal. / 11 Imp.Gal.. Under no circumstances should this dosage be exceeded and it only applies to the exclusive use of Pro-Coral Mineral.
