A too low magnesium concentration (below 1300 mg/l) results in problems maintaining correct calcium and alkalinity levels. Correct alkalinity and calcium levels are beneficial for coral growth.
Magnesium Powder from Salifert is highly concentrated and will not only increase the magnesium concentration but will also correct the ionic imbalance. Once the magnesium concentration is between approx 1300 and 1500 mg/L use Salifert's Liquid Magnesium supplement to maintain the magnesium concentration.
If magnesium concentration is low (Salifert`s Magnesium Test Kit) then you might be facing problems in maintaining sufficiently high calcium concentration and alkalinity.
Correct calcium and alkalinity values are beneficial for coral growth and health. This powdered magnesium supplement is highly concentrated and will correct the ionic imbalance. Once the magnesium concentration is between 1200–1500ppm (Salifert`s Magnesium Test Kit) revert to Salifert liquid Magnesium supplement.
Instruction:
Each level measuring beaker (30ml) will increase the calcium concentration of 40 liters with approx. 75ppm. Pre-dissolve the powder in freshwater (1 cup of water on each level beaker powder) and add slowly to the tank.
