The present invention includes a floating body and a tube body connected to the floating body, a plurality of pin-holes formed in the tube body, and a tube comprising a chelating composition injected into the tube body, the chelating composition It relates to a floating artificial reef comprising a humic material selected from the group consisting of humic acid, fulvic acid, ulmic acid, and combinations thereof, shellfish and organic feed. Metal salts contained in the fossils, amino acids and minerals obtained when various minerals dissolved in seawater and organic feed corrode are converted into chelates by humic substances so that marine organisms can consume them and prevent dewhitening of seawater. I can. In addition, by adopting a humic acid having a pore structure, it is possible to absorb odor components such as ammonia in seawater. By using the artificial reef according to the present invention, it is possible to prevent sea desertification by naturally forming a food chain in the surrounding marine ecosystem.
