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 sea water.

It is formulated to provide a safe source of iodide that will not convert to toxic free iodine under storage or reef conditions. Iodine is as toxic as chlorine and should never be used in a reef system. However, iodide is as safe as chloride.

Most iodine supplements on the market are simply potassium iodide or a medicinal disinfectant commonly known as Lugol’s Solution. Lugol’s is a highly concentrated iodine/iodide solution that is highly toxic and intended for disinfection. Although such products are sold for use in reef aquaria, we believe the risks vastly outweigh the potential minor benefits.
