A proper aerator is vital to having a healthy pond, water garden or lake no matter what time of year it is.
Use an air pump during hot weather to provide the necessary oxygen within the pond.
For Fountain Aeration see: Kasco Aeration
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.
So how much air do you need?
| Pond Volume in Gallons |
1000 |
2000 |
3000 |
4000 |
5000 |
6000 |
7000 |
8000 |
9000 |
10,000 |
Liters of air/min required to maintain Dissolved Oxygen at Koi Safe Levels |
40 |
80 |
120 |
160 |
200 |
240 |
280 |
320 |
360 |
400 |
These numbers are intended as a guideline. Your application may vary according to stocking levels. (In general terms, 40lpm per 1000 gallons is a good rule of thumb.)
