Essential Trace Mineral Supplement for Reef & Marine AquariumsKENT MARINE ESSENTIAL ELEMENTS replaces biologically important trace minerals necessary to a healthy marine aquarium. These elements are depleted by natural biological processes or removed unintentionally through protein skimming, ozone, and carbon filtration.
Add 5 ml (1 tsp) per 50 gallons of aquarium water every 1 to 2 weeks, depending on the amount of water changes performed. With frequent water changes, then add KENT Marine Essential Elements every 2 weeks. If not, then add weekly. Also add immediately after carbon use.
