Seachem Reef Iodide is an important element required by invertebrates and many soft corals (gorgonians, sarcophytons, etc). Reef Iodide is a concentrated (8,000 mg/L) stabilized potassium iodide source for reef aquaria that will restore and maintain iodide levels to those found in natural seawater.
Reef Iodide is formulated to provide a safe and easy-to-use source of iodide that will not convert to toxic-free iodine under storage or reef conditions.
DIRECTIONS: For beginner use, add 5 mL (1 capful) for each 200 L (US 50 gallons) every other day.
