MAGNESIUM complement is a concentrated (95,000 ppm) source
of magnesium for the reef aquarium designed to restore depleted levels of
magnesium to those found in natural sea water. MAGNESIUM contains no
ammonia! This is a common contaminant in every liquid magnesium
supplement on the market.
Severely depleted levels of magnesium (below 800 mg/L) can cause
depressed pH levels and an inability to maintain proper calcium levels.
Magnesium depletion is commonly associated with the use of kalkwasser.
