Stopping by GROTECH we notice their Natural Algae sheets using a special drying process. They claim that no artificial additives are used. Unlike other algae sheets these are dried, not grounded and pressed together. So you could say that the leaves were like if you harvested them from the sea and dried them. This algae contains many natural vitamins, iodine and trace elements. Just place the algae in the aquarium water for a few minutes and you are good to go. Expect to see this product in specialty reef stores soon.
