Important to know

  1. An air pump is a necessity for a pond or aquarium and serves many functions for fish and other aquatic life.
  2. Introduces oxygen into the water
  3. Provides quick and safe gas exchange, removing carbon dioxide and hydrogen sulfide.
  4. The upward movement of the air bubbles helps to circulate the water
  5. Water movement creates an ice free area during the winter
  6. Provides oxygen to beneficial bacteria (nitrifying bacteria) that help to break down waste.
