SEACHEM - Reef Iodide

Iodide is one of the important elements that especially invertebrates and soft corals like gorgonians, sarcophytes and others need. With the highly concentrated (8,000 mg/l) Seachem Iodide you supply your pets with the important element quickly and easily to maintain the iodide level in your marine aquarium.

Iodide is designed to provide a safe source of i odide that will not convert to toxic iodine, even under storage or reef conditions. Other iodine preparations often consist of potassium iodide or a lugol solution (a disinfectant). Only potassium iodide is a safe alternative, but alone it is not very effective in the aquarium due to the unstable nature of iodide. When iodide is added to the aquarium, it becomes unstable and converts to elemental iodine (biocide) and iodate (which is useless to corals, toxic in high doses, and cannot be re-measured) and iodide, which is the only absorbable form for corals. However, this instability makes potassium iodide rather dangerous. Seachem Iodide is therefore complexed so that when added, the iodide form is retained and becomes bioavailable.

Choose from these variants: 100 or 250 ml

Application: Use 1 dosing cap per 200 liters every other day at the beginning. Thereafter, change the dosage to 1ml per 80 liters of aquarium water daily to increase the iodide by 0.10 mg/l. If necessary, adjust the amount so that the iodide reads 0.06-0.08 mg/l 6-12 hours after the last administration. Use this amount daily thereafter and remeasure the iodide level periodically.

Note: It is normal that the iodide level decreases after a few days, as it depends on the chemical degradation and consumption of your corals. Therefore the dosing intervals and also amounts may vary and should be adjusted regularly by re-measuring.
