At the same time the concentration of macro-elements, such as sodium, chlorine and sulphate, continues to remain constant. Development and growth of resident organisms may be impaired due to this lack of trace elements and imbalance of ions. Regular additions of trace elements as well as water changes, helps to maintain a healthy environment for all invertebrates. Tropic Marin Pro-Coral Mineral is a highly concentrated form of the 70 trace elements that are contained in Tropic Marin© seasalt mixture. Application: 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.
