Support vibrant, thriving reef life with Seachem Laboratories Reef Iodide Supplement. This highly concentrated (8,000 mg/L) potassium iodide solution is specifically formulated for reef aquariums to restore and maintain iodide at natural seawater levels.

Why your reef needs iodide

• Essential trace element: Iodide is required by many invertebrates and soft corals, including gorgonians and sarcophytons.
• Supports growth and coloration: Adequate iodide helps promote healthy polyp extension, tissue development, and overall vitality.
• Replaces depleted elements: Protein skimming, filtration, and coral uptake can quickly strip iodide from closed reef systems.

Safe, stabilized formula

• Stabilized potassium iodide: Designed to remain in the safe iodide form under normal storage and reef conditions.
• Will not become free iodine: Unlike some iodine products, Reef Iodide is formulated so it does not convert to toxic free iodine.
• Reef-safe choice: Iodine can be as toxic as chlorine in a reef tank, while iodide is as safe as chloride when used as directed.
