Vibrance is a highly concentrated naturally stabilized potassium iodide source for reef aquaria that will restore and maintain iodide levels to those found in natural sea water. Our proprietary stabilization process makes vibranceÖ the most stable iodide supplement available. It's also the most concentrated and comes with a pipette for precision dosing. It is formulated to provide a safe source of iodide that will not convert to toxic free iodine under storage or reef conditions.
