Reef Iodide 500 ml Seachem – stabilized iodide supplement for reef aquariums

Reef Iodide is formulated from stabilized potassium iodide to provide a safe and bioavailable source of iodine for reef aquariums. It helps maintain iodide at concentrations close to those of natural seawater, without the risk of conversion into toxic free iodine.

Main Features

Role of Iodide in Reef Aquariums

Iodide is an essential element for many invertebrates and soft corals, including gorgonians and sarcophytons. It plays a key role in soft tissue growth and cellular metabolism.

In natural seawater, the iodine concentration is about 0.06 mg/L. In reef aquariums, this value can quickly decrease due to biological consumption and chemical transformations.

Benefits of Reef Iodide Formulation

Unlike Lugol's solutions or non-stabilized iodides, Reef Iodide is complexed with a stabilizing agent that prevents conversion into toxic elemental iodine or unusable iodate.

This stabilization ensures that the entire product remains in iodide form, the only form directly assimilable by corals, while limiting the risks associated with the biocidal forms of iodine.

Usage Instructions

Beginner Level

Add 5 ml for 200 L of water every two days.

Advanced Level

Add 1 ml for 80 L of water per day to increase iodide by approximately 0.10 mg/L.

Adjust the amount to achieve a concentration between 0.06 and 0.08 mg/L, measured 6 to 12 hours after the last dose.

Once the target value is reached, use this amount daily and monitor iodide twice a month.

Expert Level

After determining the iodide consumption rate, a continuous drip system can be set up.

The amount to add in the top-off water can be calculated using the following formula: m = 0.125 × v × i, where m is the milliliters to add, v is the aquarium volume in liters, and i is the desired increase in mg/L.

Notes and Considerations

It is normal for iodide levels to decrease a few days after addition, due to biological use and chemical depletion.

The amount and frequency of use can be adjusted based on the system's consumption and the corals' response.

Excess iodide can be harmful. Adjustments should always be gradual.

Do not mix directly with a carbonate supplement.
