Use the 0.01 ppm per 100 L per ml figure to calculate a dose that brings your measured reading up to target, dosing Trace Colors D at a matching 1:1 ratio, then retest before dosing again.\u003c\/p\u003e\n\u003ch3\u003eSafety\u003c\/h3\u003e\n\u003cp\u003eRed Sea states that several of the elements in the Trace Colors range become toxic above the concentrations found in natural seawater.
