Can You Over Aerate a Pond?

Can You Over Aerate a Pond?

A: There are so many benefits to aerating a pond that it’s hard to overdo it. In fact, pond and lake aeration is so beneficial it is often one of our top recommendations. Aeration infuses the water with oxygen and increases circulation, which both help your pond in a multitude of ways.

When Can You Over Aerate a Pond?

For most ponds and lakes, it is nearly impossible to aerate a pond too much. There are a few circumstances, however, when you can over aerate a pond.

  • New Aeration System: If you have a newly installed aeration system, you’ll want to start it up gradually to prevent shocking your pond. Follow your aeration system’s initial seven-day startup process. On Day 1, run the system for 30 minutes, then turn it off for the rest of the day. Then, double the time each day thereafter. On day 2, run for one hour; Day 3, two hours; Day 4, four hours, until you get to Day 7, when you will run it for 24 hours, seven days a week.

  • First Start-Up After Winter Dormancy: If you shut your aeration system down for the winter, you’ll want to do a gradual start-up after it has been dormant all winter. Again, follow our detailed instructions on a gradual aeration system start-up.

  • Game Fish and Aeration: While aeration is beneficial for fish, too much aeration can lead to an increase in the water temperature, which, in summer months, can possibly get too warm for some species, like trout. If you have recently stocked your pond, particularly if it is during the summer, start your aeration system gradually following our detailed instructions so as not to stress and kill your fish.
