Upon determination of calcium consumption using periodical tests 2 ml of \"Ionic Balancer & Trace Elements\" solution should be added for every 3 ppm calcium consumption in an aquarium of 100 liters. If you are applying the balling method add \"Ionic Balancer & Trace Elements\" solution in an amount equivalent to that of \"Calcium Blend - BallingSet Element 2\". If daily consumption exceeds 10 ml per 100 liters its recommended that solution be added over the course of a day using a dosing pump.
