Aquarium Trace Elements
Marine reef trace elements are biologically important elements that must be added to your aquarium, and replaced when they are removed by filters, skimmers and normal depletion. Marine reef trace elements are directly absorbed by invertebrates and used to grow skeletal structures or shells, or to create brilliant colors.
Below you'll find all-purpose solutions of reef trace elements; scroll further down for additional element supplements you may need depending on your bio-load (or see our pages for Calcium & Kalkwasser; Iodine and Iodides; and Strontium and Magnesium for more information). Always monitor important trace elements in your tank and adjust as needed!
