Coral Essentials Magnesium + 500mL Light & Heat is the level of bicarbonateThe DALUA collaboration with Coral Essentials. Magnesium plus traces is a concentrated source of liquid magnesium, 20,000 ppm (mg L). Coral take up magnesium into their calcium carbonate skeletons. It is important to maintain adequate magnesium levels as this is essential in maintaining correct calcium and alkalinity levels. Poor magnesium levels usually result in the need for addition of much higher levels of calcium and carbonate than would normally
