Not just Potassium Iodide like many other supplements. The NatuReef® formulation contains the forms of Iodine that are found in natural seawater. Your inverts will love it! Also, along with Iodine we provide a bonus of calcium. Your corals will really love that! That’s not all. For the more sophisticated filter feeders such as tunicates, sponges, etc. we’ve included a little Boron, Molybdenum and Vanadium. So they also love it.
