A proper aerator is vital to having a healthy pond, water garden or lake no matter what time of year it is.

While there are many components that comprise a healthy Koi pond there is probably none more important than that the of having the proper aeration system. Aeration is defined as adding oxygen to water and is an essential part of any healthy Koi pond.

The function of an aerator is to keep the water from becoming stagnate, to aid in the movement of the water through the filtration system and to supply needed air to the fish. The best position for your aeration system is as close to the filtration system as possible.

The following figures are intended as a guideline in selecting the proper aeration system according to the size of your pond.

Liters of air/minute by number of gallons of water:
40 liters of air per minute for 1,000 gallons
80 for 2,000, adding an additional 40 liters of air per minute for each additional 1,000 gallons.

Temperature, atmospheric pressure and altitude also play very important roles in the amount of oxygen water will maintain and will vary according to each and most be taken into consideration when aerating your pond..

One safety note, never place an air bump below the water level because if there is ever a loss of power, the water will back-up, destroying the system as well as causing various electrical risks.

Use an air pump during hot weather to provide the necessary oxygen within the pond.

During the winter a pond aerator will keep an opening in the ice, add oxygen and help gas off toxins.

Any pond will benefit from additonal aeration. A pond air pump will also help the growth rate of your koi or goldfish.

Adding an aerator will also help the biological process within your pond. Biological filtration requires large amounts of oxygen so an air pump should be used.
