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.

  1. Make sure that your electrical voltage is compatible with voltage printed on the air pump label
  2. Always use a properly grounded electrical outlet
  3. To avoid electrical shock and/or electrical short, use a drip loop to prevent water travel along the power cord
  4. Only use a proper rating extension cord when needed.  A cord rated for less amperes or watts than air pump rating may over heat.
  5. Air pump should be placed above the water level for maximum performance
  6. If the air pump accidentally falls into the water, unplug the unit first before retrieving it from the water
  7. Do not install or store air pump where it can be exposed to extreme weather conditions or temperature below freezing
  8. To avoid electrical shock: do not operate air pump if it has a damaged cord or a wet plug
  9. To prevent damage to the air pump: air stones should be cleaned or replaced periodically.  This allows the air pump to run with minimum back pressure, allowing the diaphragm to last longer
  10. Do not attempt to repair air pump at home.  If service is needed, return air pump to an authorized service center for service.
  11. Make sure that the circuit to your pool is protected by a GFI outlet and a fuse or by a GFI circuit breaker
