Magnesium (Mg) is important in helping Ca and Kh interact properly. If Mg is low, Ca and Kh levels will not properly be maintained as they precipitate out of aquariums. This causes the need to increase Ca and Kh to reach our target levels which wastes chemicals.  Target range for Mg is 1280-1380.  Test appropriately.  Often when Ca and Kh levels become unbalanced it is due to low Mg.  For best results, MECoral Mg should be used with MECoral Calcium and Alkalinity.

Quick Guide: To raise Mg 10 ppm (1280-1290) in an aquarium with 100 gallons of seawater,  add 80 ml or 2.7 fl oz.  Test as need

Ingredients:  Pharmaceutical grade USP Magnesium Chloride Hexahydrate, Pharmaceutical Grade USP Magnesium Sulfate Anhydrous
