Size: magnesium ions are smaller than calcium ions, so more of them fit in the same volume, even when surrounded by water.
Magnesium in Drinking Water
The wells close to the mountains have, in general, more magnesium than calcium while those closer to the ocean have slightly more calcium than magnesium. All these Honolulu well sources are interconnected in the municipal water system so that one could get mountain source water one day and seacoast source water the next.

Group 2 The Alkaline Earth Metals
Calcium metal reacts with water, evolving hydrogen gas at a rate rapid enough to be noticeable (unlike its sister magnesium) but not fast enough at room temperature to generate much heat. Part of the slowness of the calcium-water reaction results from the metal being partly protected by insoluble white calcium hydroxide.

Alkaline earth metal — Wikipedia Republished // WIKI 2
The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.
Barium - Simple English Wikipedia, the free encyclopedia
Barium is too reactive as a metal, so it is not found in the earth as a metal. It is found in chemical compounds. Barium only occurs in one oxidation state: +2.Most barium compounds are colorless. The ones that dissolve in water or stomach acid are very toxic.
