ReefGrow uses pure USP concentrated grade iodide stable ions. Designed for hobbyist who want to maintain the utmost stable systems to provide optimum coral growth and health.
Having iodide levels found in natural seawater available at all times in a form that is readily absorbed by corals and inverts allows for better reef health. ReefGrow recommends keeping levels of iodide to that of natural seawater, which has an average of about .04 to .06 ppm. It is not necessary to maintain high levels of iodide, and in our lab testing and research we have actually found that high levels can actually cause issue with some corals such as Goniopora.
Unlike other competitors products, all ReefGrow products can and should be for optimum health, used daily and can be used within mere minutes of each other.
