Air Pumps and Diffusers by Hakko
Of all the essential elements in water, oxygen is also in the shortest supply. The air we breathe is 21% oxygen. Water can only hold about 8 parts per million (mg/liter) or 0.0008% at 68 degrees F. Oxygen does not like water. It does not take long for oxygen to be depleted; it is our job to make sure it is replenished continuously. Our fish depend on us. 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.
