JBL TraceMarin 2 is an iodine supplement formulated for salt water aquaria. JBL TraceMarin 2 also contains fluoride, boron and chromium for the professional care of your reef aquarium. These ions are needed for the growth and development of all hard corals, soft corals, bivalves and other invertebrates as well as calcareous algae in your reef aquarium. In order to avoid the incompatibility and reaction of certain elements with each other, JBL have formulated 3 products, which have been designed to be used in combination, to provide the best possible professional care for reef aquariums: JBL TraceMarin 1, 2 and 3. JBL TraceMarin 2 contains no colourings, additives or complex-forming ingredients (chelators), as these have proved to be problematical in the care of reef aquariums. Please refer to the product guidelines for the amounts to use and the optimum frequency of use.
