An aquatic-based algae production apparatus employing a microalgae production support assembly (30) and a cluster of six floating, closed loop, flatbed, CO2/O2 gas-permeable, photo-bioreactors, offering an economical solution for microalgae industrial production. The apparatus's bioreactors are submerged in the proximity of the water surface mark (20) for maximum light exposure and for CO2/O2 continue diffusion. A microalgae processing and control assembly (200) is monitoring the algae growth for each photo-bioreactor in the cluster, and is cyclically harvesting the microalgae. After harvesting the microalgae are transferred into a submerged variable-volume microalgae storage tank (250). Solar photovoltaic panels (400) and (500) are supplying the energy required for the operation of the apparatus. Swivel electrical propellers (330) attached to the bottom of the apparatus protective outer barrier (300) are controlling the apparatus's water deployment.
