Under normal conditions, iron is virtually impossible to maintain at measurable concentrations in seawater. Natural seawater concentration for iron is about 0.01 mg\/L. Iron is important in planted aquaria and should be maintained between 0.1 to 0.2 mg\/L.\u003c\/p\u003e\n\u003cp\u003eMultiTest™ Iron measures both ionic and most chelated iron in freshwater or marine water to less than 0.05 mg\/L.
