An aerobic treatment system includes a plurality of highly porous, high surface area, inert, synthetic, inorganic, or natural material particles, having a specific gravity of less than 1.0 that float on an enclosed aqueous environment whereby plants and/or microbes can be grown thereon and/or animals such as fish can be raised therein. The inert particles trap air bubbles and nutrients for the growth of diverse types of plants, animals, or microbial systems, which enable phyto treatment of an aqueous waterbody with the ability to limit the growth of unwanted plant and algae such as blue-green algae. The above aerobic bio treatment system contains desirably bioremediation media having one or more microorganisms that are able to withstand system shocks while minimizing energy usage associated with aeration. The system can generally be utilized in any aqueous environment such as waste water and/or polluted water in an enclosed area such as a container, tank, pond, lake, or the like.
