E.S.V. Through the chemical process known as "ion-pairing", magnesium ion concentration influences the saturation point for calcium corbonate in solution. In general, the further the magnesium concentration drops from natural seawater levels (1350 ppm), the more difficult it becomes to maintain adequate levels of both calcium and alkalinity. Magnesium also plays an important role in stabilizing pH by interacting with the buffer system of seawater. B-Ionic Magnesium is an easy to use one component liquid supplement which, when used with B-Ionic Calcium Buffer or kalkwasser, will not disrupt the ionic balance of closed marine aquaria. B-Ionic Magnesium does not contain nitrates, phosphates, organics, or chelating agents. B-Ionic Magnesium contains 36,000 ppm magnesium, and one mL will raise one gallon of aquarium water by 10 ppm.

REVIEW
Easy to use with E.S.V. B-Ionic Calcium/Alkalinity 2-part. Got my SPS happy and growing again using these products. My only regret was I ordered a twin reefdoser pump instead of a triple. I have the Aqua Medic Reefdoser which I highly recommend also.
