A bubble generator includes an air intake device, an air guide device, an aeration disc and a rotating device. The air guide device is partially immersed in liquid and guides air flowed into the air guide device through the air intake device toward the liquid. The aeration disc produces negative pressure by being rotated in the liquid and moving the liquid whereby air guided by the air guide device produces air bubbles in the liquid. The aeration disc comprises one or more blades that spin to create a vacuum of air moving downward through the air intake device and air guide device and into the liquid, and an arcuate wall that comprises one or more slots.
