Info: Seachem Reef Iodide™ Dosing Instructions

BEGINNER: Add 5 mL (1 capful) for each 200 L (US 50 gallons) every other day.

ADVANCED: Add 1 mL for each 80 L (20 US gallons) daily to raise iodide by 0.10 mg/L. If necessary, adjust amount so that iodide reads 0.06–0.08 mg/L 6–12 hours after the last amount. Thereafter, use this amount daily and check iodide twice a month.

EXPERT: After determining the iodide consumption rate, set up a continuous drip system. Use the following formula to determine how much to add to your top-off water: m=0.125vi (m=mL of product to add to top off water, v=volume of tank in liters, i=amount to raise iodide in mg/L). For example, if you want to raise iodide by 0.10 mg/L in a 200 liter tank, then you would add 0.125x200x0.10=2.5 mL into the top-off water. [For reference: 1 gallon=3.8 L].

Notes: It is normal for iodide levels to decline after a few days. This results from utilization and chemical depletion. Therefore, amount and/or frequency of use can be varied. Amount used can be adjusted based on coral response. To check iodide levels use Seachem’s MultiTest™ Iodine & Iodide test kit.
