Abstract: Light, heat, gas exchange, and water motion are all required elements to sustain aquatic photosynthetic organisms. Rather than providing separate systems, a flux of photons appropriate for photosynthetic organisms, including algae, is dispersed throughout the surrounding water. A gas source performs water movement and circulation by acting as an airlift pump while performing a liquid-gas mass transfer. Finally, heat is added to the surrounding liquid by a heat source or the light source, which increases the rate at which microorganisms grow and improve efficiencies. By combining these necessary components for aquatic life support, efficiencies are increased, costs are saved, and photosynthetic organism growth is regulated.
