It is the lower hydrate when compared to bieberite (heptahydrate) and moorhouseite (hexahydrate), and a higher hydrate when compared to cobaltkieserite (monohydrate). It occurs together with moorhouseite within efflorescences.<ref name=JB/><ref>{{cite web|url=http://www.mindat.org/min-282.html |title=Aplowite: Aplowite mineral information and data |website=Mindat.org |accessdate=2016-03-03}}</ref>
