Magnesium and Iron are two important nutrients use by many reef inhabitants including corals and macroalgae. Magnesium also plays an important role in maintaining correct balance between calcium and alkalinity in seawater. It helps stabilize alkalinity and calcium levels by preventing excess precipitation of calcium and bicarbonate.
For a concentrated liquid magnesium supplement at a great value, we recommend Kent Marine Tech-M. This ionically balanced formula safely raises magnesium levels in marine aquariums. Tech-M promotes healthy coral growth by increasing magnesium levels necessary to maintain support optimal alkalinity and calcium levels.
