Marine Aquarium Trace Elements
Saltwater 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. Our saltwater trace elements recreate the natural conditions needed by marine fishes. We even have trace elements for brackish water aquariums.
Additional trace elements are needed by corals and invertebrates, so if your tank is not fish only, we recommend using a product made for fish and invertebrates, or using reef trace elements.
