ZEOmag is a magnesium granulate designed to be used with standard calcium carbonate media in a calcium reactor. It is most commonly mixed with standard calcium reactor media so that the ZEOmag comprises 10-30% of the mix. Primary benefit of using a media like this is it is one of the very few methods of maintaining magnesium levels in the aquarium without adding additional chloride or sulfate.
ZEOmag is a pure source of magnesium granulate with a coarse grain size of 6-12 mm. Ideal addition to any calcium reactor.
