Balance air for all of us

Oxygen and Carbon Dioxide What Makes Water Healthy?If you’ve ever played on a see saw, you know that it’s important to have the two sides equally balanced. In a lake, a good balance of oxygen and carbon dioxide is just as important.

Underwater plants and algae also contribute oxygen during the process of photosynthesis.

An indiect way to check the Oxygen production in an area can be conducted by checking the water Oxygen content or dissolved Oxygen.
Dissolved oxygen, also called DO, is vital to the health of aquatic habitats. Plants and animals need oxygen to survive. A low level of oxygen in the water is a sign that the habitat is stressed or polluted.Where does oxygen come from? Oxygen from the air is mixed into water with the help of rain, wind, waves and currents. Fast-moving water contains more DO than still water because it has more contact with the air, allowing more oxygen to mix into the water. Underwater plants and algae also contribute oxygen during the process of photosynthesis.
