[Suggested Interval] As required [Description] The use of Granular Activated Carbon (G.A.C.) can be important in removing chemical waste products commonly found in aquarium systems. In a freshwater aquarium, it is recommended to run carbon continuously in your aquarium, changing it once every 30-45 days. In marine aquariums, carbon is only used when required as it can possibly remove important trace elements required for invertebrates. If you decide to use carbon on a continuous basis in a marine aquarium, be sure to add trace elements if required and change the carbon once every 30 days. [Task]
