A synthetic structure is used to simultaneously provide food, shelter and reproductive support for many aquatic species. Synthetic seagrass may be produced in the form of flexible mats with a plurality of ribbons. The lower ends of the ribbons are anchored to the benthos. The other ends of the ribbons are buoyantly supported in the photic zone. The ribbons may be economically produced in plural coextensive layers, with one layer providing buoyancy and the other layer being structured to enhance biological growth. The system may be tailored for use in desired applications by selecting the surface area structure, ribbon spacing and density, and other parameters. The system may be used to remove nutrients and/or toxic materials from water. The invention may be used to simultaneously promote aerobic and anaerobic reactions to control water quality. The invention also relates to artificial plants, including seagrass mats, for aquariums. The artificial plants may be flexible and buoyant. The artificial plants may promote the growth of fish food in the aquarium, and they may perform other biological functions.
