Oxygen is the most important element for life.
All life revolves around the availability of Oxygen. In aquatic
environments like fish ponds, oxygen is the single most limiting factor
for success. All aquatic life forms demand oxygen. From the fish down
to the bacteria any body of water has what is called an “oxygen
Of all the essential elements in water, oxygen is also in the
Ponds and lakes gain oxygen in two ways:
- Photosynthesis by algae and plants.
- Atmospheric oxygen is transferred into water at the surface of
Photosynthesis may produce sufficient oxygen for very low fish loads
but is inconsistent due to the fact that at night algae and plants
remove oxygen through the process of respiration. Most of the ponds and
lakes we deal with have higher than natural fish loads and require
additional oxygen to maintain a clean and healthy environment.
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
