Matala Hakko air pumps can be used to create a huge column of bubbles or "air lift" rising from the bottom of a pond or lake. This brings oxygen depleted water to the surface where the bubbles burst and create tremendous surface turbulence, circulation and aeration. HAKKO air pumps used in this manner will literally breathe life into your pond or lake.
