For monitoring magnesium levels in marine aquariums easily and safely. 


Often overlooked, magnesium plays a critical role in chemical and biological processes in an aquarist's saltwater aquarium. The magnesium content in natural saltwater is only behind that of sodium and chloride, making it a major element as opposed to a trace element. Magnesium is essential to all organisms for biological functions, and is very important to organisms that are skeleton building such as LPS and SPS corals.

Before dosing anything, you need to know where you're starting, so test your aquarium's water. Magnesium levels in a reef aquarium should be between 1250 and 1350 ppm. Since each aquarium is different, it will use magnesium at its own rate.
