SeaChem Reef Iodide is an iodide supplement for those with dense populations of invertebrates or soft corals. It is also useful in tanks with aggressive skimmers. Reef Iodide is concentrated at 8,000 mg/L. As little as 1 mL in 160 Liters (40 gallons) will raise iodide to natural seawater concentration. It is formulated to provide a safe source of iodide that will not convert to toxic free iodine under storage or reef conditions. It is recommended that this product be used with the MultiTest: Iodide test kit to ensure proper maintenance of iodide levels. 250 mL treats 20,000 L (5,000 gallons).
