Seachem Reef Iodide™ is a concentrated (8,000 mg/L) source of stabilized potassium iodide specifically formulated for the reef aquarium. Iodine is a critical element required by many soft corals (such as Xenia and Gorgonians) and is essential for the successful molting of crustaceans like shrimp, crabs, and lobsters. Unlike iodine supplements that use unstable molecular iodine (which can be toxic in high concentrations), Reef Iodide™ utilizes a stabilized complex that is safer for inhabitants while remaining highly bioavailable for biological uptake.
Reef Iodide™ provides a safe and effective way to maintain the trace levels of iodine depleted by protein skimming and biological consumption.
Supports Crustacean Molting: Provides the essential iodine required for shrimp and crabs to shed their old exoskeletons and develop healthy new ones.
Soft Coral Growth: Specifically beneficial for the health and expansion of Xenia species, mushrooms, and leather corals.
Stabilized Formula: Engineered to remain in a usable state longer than standard iodide products, preventing the rapid "drop-off" of levels often seen after dosing.
Safe for Livestock: Formulated to avoid the toxicity associated with free iodine (Lugol's solution) when used as directed, making it safer for delicate reef systems.
High Concentration: A single 250ml bottle provides enough supplement to treat several thousand gallons, making it an efficient choice for large or high-demand systems.
How much Seachem Reef Iodide™ should I dose? Add 5 mL (1 capful) for every 200 L (50 US gallons) every other day. If you have a high density of soft corals or invertebrates, the frequency can be adjusted based on testing.
Can I overdose on iodine? Yes, iodine can be toxic if levels become too high. It is always recommended to use a high-quality test kit to ensure your levels stay within the natural seawater range of 0.06 mg/L.
Will this affect my protein skimmer? No, Reef Iodide™ is formulated to be compatible with all modern reef equipment. However, be aware that heavy protein skimming is one of the primary reasons iodine needs to be replenished regularly.
Should I turn off my UV sterilizer when dosing? It is not strictly necessary, but turning off UV or Ozone for 30–60 minutes after dosing can help maximize the bioavailability of the supplement before it is potentially oxidized.
Seachem Reef Plus™: A comprehensive supplement of vitamins, amino acids, and trace elements that works alongside Reef Iodide™ for total coral health.
Seachem Reef Strontium™: Essential for stony corals and calcareous algae, providing the other major trace element often depleted alongside iodine.
Seachem MultiTest™ Iodine & Iodide: The recommended precision test kit to monitor your dosing and ensure a safe environment for your invertebrates.
