Corals might require iodine as a de-toxifier, as a protection against uv-radiation and as a natural defense against many parasites.
Iodine is present in NSW (Natural Sea Water) in a very low concentration (0.06 mg/L or 0.06 ppm). Iodine occurs in NSW as different species. These include iodide, iodate, molecular iodine and hypoiodite. Generally, when we say iodine, we mean one or more iodine species without a clear distinction being made. NSW contains predominantly iodate and to a lesser extent iodide. There is however a misconception among many hobbyists that iodide predominates in NSW. Research by Salifert and universities has proved this to be untrue.
About Natural Iodine
Salifert’s Natural Iodine supplement contains a large portion iodate and also some iodide in similar proportions as NSW. All ingredients are of a pharmaceutical quality or even better. This ensures that no unwanted elements are added to your valuable aquarium. Other requirements: for excellent results try also our high-quality calcium, strontium, alkalinity and trace elements supplements.
Directions for Use:
Shake before use. Regular maintenance: Dose 5 ml per 100 liters (25 gallons) once every 2 or 3 weeks. Adjust dosage according to individual requirements (use an iodine test, e.g., Salifert’s Iodine Profi-Test). Every 5 ml per 100 liters (25 gallons) will increase the iodine concentration (that is iodide +iodate) by approx. 0.04 mg/L.
Keep out of reach of children. In case of contact with eyes rinse with plenty of water. Only for aquarium-hobby use. Not for human consumption (directly or indirectly)!
